Licensing of 450 MHz RTK BaseSH20560,0000118 1908DEC091/1Licensing of 450 MHz RTK BaseThe 900 MHz RTK product sold by John Deere uses ISMband radios. These radios do not require licensing by theend user. The radios are limited to a specific frequencyrange and 1 W maximum output power. While this systemworks for the majority of applications, the reliability of theRTK link may become limited when passing through treesand dense foliage.The intent of 450 MHz RTK is to increase the range andreliability of the RTK link. To overcome the attenuationof adverse field conditions, transmission power greaterthan 900 MHz RTK is needed. While there is some addedbenefit from using a radio with lower frequency and longerwavelength, the signal strength is the dominant factor inthe radio link reliability. To legally transmit at a higherpower, 450 MHz RTK uses a licensed band radio. The enduser of the licensed band transmitting radio is responsiblefor obtaining and maintaining a valid site license from thelocal spectrum authorities. In 450 MHz RTK system, thisrequires a license for each base station.Vehicle radios in 450 MHz system are not transmitters.Since they only receive corrections from the base, 450MHz vehicle radios do not required a site license.An end user can apply for the license by applying directlyto the local spectrum authority:Country AuthorityAustralia Australian Communications and Media Authority(ACMA)Canada Industry Canada (IC)United States Federal Communications CommissionNew Zealand Radio Spectrum Management GroupAn end user can also apply with the aid of a frequencycoordinator. A frequency coordinator is a private companythat has been certified by the local frequency spectrumauthority to recommend and aid in the application for alicenses. For a fee, these third party coordinators willreduce the complexity and confusion of the applicationprocess. However, the final responsibility of the licensestill resides with the end user.Check www.StellarSupport.com for country specificinstructions on how to obtain a site license.IMPORTANT: Please contact your local radioauthorities or partnering frequency coordinatorfor region specific regulations and licensing.License Renewal ScamsAfter being granted a license for 450 MHz RTK radio,base station operators should be aware of licenserenewal scams. Spectrum licenses are public record.Other companies could retrieve licensee informationand then mail current license holders offers to prepareapplications for license renewal. The letters containwarnings that there will be monetary penalties if thelicensee does not comply. These companies are notaffiliated with government spectrum authorities. They aretaking advantage of the public record and the licensee’sdesire to comply with the law. Their intention is to chargea “processing” fee on top of the actual amount that alicensee would pay for renewal. While it is important tonot let your license expire, licensees should work directlywith their local spectrum authority or a certified frequencycoordinator. Internet searches of the companies involvedusually identify if the company is relevant.101 121509PN=10
RTK Base Station SetupSH20560,0000119 1907DEC091/1System OverviewThe StarFire™ RTK system consists of a local basestation permanently mounted on a structure that transmitshigh accuracy corrections to the vehicle’s StarFire™receiver using 450 MHz RTK radios and an optionalamplifier. The StarFire™ receiver on the RTK equippedvehicle must have a direct line of sight with the basestation in order to receive the RTK signal. While the highertransmission power and longer wavelength of 450 MHzRTK aids in the transmission through trees and foliage, itwill not penetrate through earth in hilly terrains.Performance of the RTK correction is related to theoperating distance from the base station. When operatingbeyond 20 km (12 mi.), degraded accuracy will occur andit may take longer to initially acquire the RTK signal.IMPORTANT: The 900 MHz and 450 MHz RTK radiosystems are not compatible. Vehicles with 450MHz radios must receive corrections from a450 MHz radio attached to the base. Likewise,vehicles with 900 MHz radios installed mustreceive there corrections from a base with a900 MHz radio installed. Different radio modelscan not communicate with each other sincethey transmit on different frequencies.StarFire is a trademark of Deere & Company151 121509PN=11

RTK Base Station SetupSH20560,000011B 1908DEC091/1Base Station SetupThe base station is the most critical part of RTK system.During installation, care must be taken to ensure the basehas problemfree operation. There are two issues thatare responsible for most problems with a base station:Shading and Multipathing. If a base station experiencesone of these problems, it could be detrimental to your RTKoperation. These issues are shared with the 900 MHzRTK system. Mitigation techniques have already beendocumented in the standard StarFire iTC – RTK manualthat came with the iTC receiver. This manual providesdetailed recommendations to minimizing these errors.Base station operating mode can be either AbsoluteSurvey Base Mode or Quick Survey Base Mode.Once you have installed the base station receiver,installing the radio in a location to best maximize theoutput, can be a challenge. Below are several optionscurrently available through John Deere.•Leave the RTK radio in its original configurationattached directly behind the base station receiver.•Use PF80821 extension harness [92 m (300 ft.) inlength], moving the radio from the back of the basestation receiver to an elevated position, and running theharness in between.NOTE: It is important to use the PF80821 harnessand grounding wire properly according to theinstallation instructions. This harness hasbuilt in protection for both your radio andreceiver for unwanted electrical transientsdeveloped on the harness.IMPORTANT: The antenna must be installed beforethe radio module is powered ON.Avoid water intrusion by keeping theantenna attached whenever possible.Removing the antenna while transmittingmay damage the radio module.IMPORTANT: If using coaxial cable between theradio and the antenna, you need to usethe lowestloss cable available or you maysuffer RTK radio link range issues.•Attach the RTK radio in a secured location and runlowloss coaxial cable between the radio and theantenna.NOTE: When using this option, it may be necessary toinstall a highergain antenna and/or the optionalamplifier to compensate for loss.450 MHz RTK Radio SpecificationsModel Number PF81428Frequency Range 435470 MHzBandwidth Options 25 or 12.5 kHzModulation 2 and 4 level GFSKRF Baud, 25 kHz BW 19.2 kbps at L2RF Baud, 12.5 kHz BW 9.6 kbps at L21400 at 25 kHzFrequency Channels2800 at 12.5 kHzOutput Power 0.22 WSensitivity 110 dBm for 10^6 BERIn/Out Impedance 50 ohmOperating Voltage 915 VOperating Temperature 30 to 60° COut RF Connectors Female TNCControl Connector 4pin DeutschEvery 450 MHz radio comes standard with 2 dBi whipantenna that has a TNC connection.450 MHz Whip Antenna SpecificationsModel Number PF81464Gain 2 dBiFrequency Range 450470 MHzImpedance 50 ohmVSWR < 2:1RF Connector Female NTypeLength 13.2 in.

Read and follow PREVENT ELECTRICALSHOCK AND FIRES and AVOID EXPOSURETO HIGH RADIO FREQUENCY FIELDS inthe SAFETY section.The primary reason for 450 MHz RTK is to provide a morerobust RTK data link. Signal strength is the dominantfactor in the link reliability and range. For areas wherethere are trees and other foliage, John Deere offers anoptional inline amplifier.The PF81443 amplifier is a UHF RF power amplifierintended for use in 450 MHz RTK system. It is notintended to be used with 900 MHz RTK or any otherapplications. The amplifier can deliver RF power from 0to 50 W proportional to the 0 to 2 W input from 450 MHzRTK Radio. It covers a frequency range from 450 MHz to470 MHz. This higher signal strength provides greaterrange from the base and increased coverage in areaswith dense foliage and trees.This amplifier is inserted between the radio and the baseantenna. The amplifier has been designed to functionoutdoors attached to its mounting plate with sun shade.Mount the amplifier in an area where air can freelycirculate around it. If possible, mount in a location shadedfrom direct sunlight.Operation of the amplifier inside an enclosure is notrecommended. Poor ventilation within the box cancause the amplifier to overheat. While this would notpermanently damage the amplifier, it would cause it toPUPC000027 —UN—06DEC09Amplifier Assemblystop amplification.

RTK Base Station SetupContinued on next page SH20560,000011D 1908DEC093/4The ability to use a single base station is a substantialreduction in cost and maintenance. The drawback to thismethod is that only one radio can be configured at a time.A single RS232 port is used by the StarFire™ receiverto communicate with an RTK radio. Two radios cansimultaneously receive RTK corrections from the receiver.Unfortunately, the receiver can not process simultaneousmessages sent from the radios. The two radios senddifferent messages and interfere. To ensure that thisinterference does not occur, the dual radio harness hasthe radio send wire in only one branch.To prevent network connection errors, a specificprocedure must be followed when configuring a basestation supporting two radios:1. Connect the Dual Radio Harness to the StarFire™Receiver.2. Power the base station StarFire™ Receiver with only900 MHz connected to 4wire Deutsch connector. Thereceiver must have clear view of the sky.3. Once the receiver determines its position, configure900 MHz radio Network ID and Radio Channel.4. Power down the base station StarFire™ Receiver.5. Disconnect 900 MHz radio and then connect 450 MHzradio to the 4wire Deutsch connector.6. Once the receiver determines its position andrecognizes the radio, configure 450 MHz radio tocomply with the site license.7. Power down the receiver.8. With 450 MHz radio still attached to the 4WireDeutsch connector, connect the 900 MHz radio to the3wire Deutsch connector.9. Power the base station.IMPORTANT: Do not attempt to change the radioparameters while both radios are attached.This can corrupt the configuration of 900 MHzradio and may cause problems with roversliking to it. If this does occur, reconfigure theradios with the process given above.During normal operation, ensure that 450 MHzradio is connected to the 4wire connectorand that 900 MHz radio is connected to the3wire connector. If the receiver detects a900 MHz radio, 450 MHz radio link may becompromised. At its lowest data speed, the450 MHz radio does not have the capacity totransmit corrections at the 900 MHz radio rate.PUPC000007 —UN—03DEC094Wire RTK ConnectorPUPC000008 —UN—03DEC093Wire RTK connectorVehicles using 900 MHz will see fewer messagesreceived when using a dual radio base station as theircorrection source.

For 450MHz RTK, these settings can be controlled and are theresponsibility of the end user. Besides the Network IDon the RTK Main screen, there are four parameters thatmanage the radio link between the vehicle and Base:Radio Frequency, Bandwidth, Data Rate and Power.The Radio Frequency is the center frequency of the linkshared between the Base and Rover.The Bandwidth is the range of the frequency that thetransmitted signal is modulated. This range, or band, iscentered about the Radio frequency. For example, if theradio is set at 460 MHz with a bandwidth of 12.5 kHz, thenthe radio link will be contained within 460 ± 0.0125 MHz.The Data Rate is the overtheair speed of the data link.This baud rate is directly related to the bandwidth settingof the radio. The signal to noise increases with largerbandwidth. A larger bandwidth is therefore related tohigher baud rates. Two Data Rate settings are providedfor each bandwidth. L2 is the lower speed and providesthe maximum radio link range.

RTKaccuracy is expressed as an absolute value (without +/)because RTK performance is not subject to GPS drift overtime. RTK accuracy levels are described on a static basismeasured at the vehicle receiver, 68 percent of the time,within 12 mi.

For the RTK application, this is theline between the base and vehicle antennas. Typicalobstructions include:•Trees and foliage•Buildings or other manmade objects•Terrain variation, such as hills or valleys•Curvature of the EarthThe higher RF power of 450 MHz RTK will reduceattenuation due to plants and small variations in terrain.Blockage due to manmade objects can be reducedthrough planning of the base antenna location. Similarto analysis performed to locate the StarFire™ receiverinstallation, the transmitting antenna should be locatedaway from nearby obstructions.To deal with obstructions away from the base, small terrainvariations and the curvature of the Earth, the antennashould be placed as high as possible. The local spectrumauthority will limit the range and potential interference ofthe base station signal by setting a maximum power andmaximum antenna height. End users should install theirbase antenna to the maximum height allowed for bestperformance.StarFire RTK™ retains its published accuracy to 12 mi.(20 km). If consistent with the granted site license, it isrecommended that antennas are mounted ≥ 30 m (100ft.) to ensure the full range of coverage.

Wide bands have more data capacity and fastermessage transmission than narrow bands. In the RTKsystem, this results in a more robust data link. However,the disadvantage to using a larger bandwidth is that fewerlicensed frequencies are available to applicants. To moreefficiently use the available frequencies, some spectrumauthorities are transitioning from older wideband licensingplans to narrowband licensing plans.For example, in the United States the FCC has establishedJanuary 1, 2013 as the deadline for migration to 12.5 kHztechnology. Applications for wideband operations (25kHz channels) will be accepted until January 1, 2011. Allexisting Part 90 radio systems operating on frequenciesbetween 150512 MHz have eight years to convert thosesystems either to 12.5 kHz bandwidth or to a technologythat provides one voice path per 12.5 kHz of bandwidth orprovides a data rate of 4800 bps per 6.25 kHz.L2 versus L4 GFSK ModulationThe 450 MHz RTK radio is a digital transmitter. There aretwo possible modulation techniques that can be set in 450MHz RTK radio: Level 2 (L2) or Level 4 (L4) GaussianFrequencyShift Keying (GFSK).When transmitting with L2 modulation, 1’s and 0’s aresent by shifting the frequency between two possiblestates about the center frequency within the bandwidth ofthe radio. The “Gaussian” term refers to a technique ofsmoothing the transition between the two frequencies.When transmitting with L4 modulation, the radio shiftsbetween four frequencies about the center frequency.This allows four different symbols to be sent during asingle transmission: 00,01,10,and 11. This results in 2xthe overtheair speed as the L2 modulation technique.The drawback is that the signal to noise is lower withthe L4 technique relative to the L2. This is because thevehicle radio must differentiate between 4 frequenciesinstead of only 2.The default modulation for the 450 MHz RTK is L2. Thisprovides the greatest RTK range. L4 will be an advantagein selected applications. One example is operation nearthe base where small objects frequently block the lineof sight. Here the signal strength is sufficient for L4.The higher baud rate results in short transmission times.These messages then have a lower probability of beingblocked.Operation of Vehicle Next to BaseDepending on the base station setup, operation ofvehicles directly under or next to the base may be limited.The 450 MHz system has both higher power and highersignal sensitivity than standard RTK. A consequence ofthis is that radio signals in the immediate vicinity of thetransmitter may be too strong for the receiving radios. Forbase stations that serve vehicles at both ≥20 km and ≤1 km from the base, it may be necessary to add inlineRF attenuators to the rovers operating directly underthe base. Attenuator specifications: RF load of 15 dBm,capable of 2W, inline female TNC to male TNC.303 121509PN=32
