There are no user-serviceable parts in the antenna and no maintenance is required. When the GPSCard status code

indicates that the unit is faulty, replace with another unit and return the faulty unit to NovAtel Inc.

You must obtain a RETURN MATERIAL AUTHORIZATION (RMA) number by calling GPS Customer Service at

1-800-280-2242 (North America only) or 403-295-4900 before shipping any product to NovAtel or Dealer.

Once you have obtained an RMA number, you will be advised of proper shipping procedures to return any defective

product. When returning any product to NovAtel, please return the defective product in the original packaging to avoid

ESD and shipping damage.

Antenna Model 600-G

- User Information -

INTRODUCTION

The performance of the Model 600-G can be summarized as follows:

• Very good sensitivity to right hand circularly polarized signals over a wide range of

elevations and in all azimuth directions

• Excellent amplitude radiation pattern roll-off near the horizon, in effect eliminating

multipath-generated replicas of the original line-of-sight (LOS) signal

• Very good axial ratio, thus ensuring that a high quality signal is received

• Common location and stable phase center for all four channels (GLONASS and GPS

L1 and L2). The phase center in the x and y-axis is located in the center of the

antenna for all channels due to its inherent symmetry and co-centric type design.

• Enhanced immunity against electromagnetic interference

• Better radiation “hardening” from lightening or EMP (electromagnetic pulse) effects

• High-speed transient voltage suppressor

• Operational temperature range from cold to hot extremes

The Model 600-G can be distinguished from other GPS-600 models by its red rim.

DESCRIPTION

The Model 600-G antenna is an active antenna designed to operate at the GPS and

GLONASS L1 and L2 frequencies. The slot array antenna element is coupled to a low-

noise amplifier (LNA). The unit is optimized to receive right-hand-circularly-polarized

signals. Its radiation pattern is shaped to reduce signals arriving at low elevation angles.

These features decrease the errors associated with electromagnetic interference and

multipath.

The Model 600-G antenna is intended for surveying and other kinematic positioning

applications. The sealed radome allows the antenna to be used in severe weather, marine

applications and hostile environments. The unit's compact size and light weight ensure its

portability.

Both the input DC power and the output RF signal flow over a single coaxial cable

connected to the unit's TNC female connector.

To mount the antenna, ensure the adapter is screwed into the antenna base (finger tighten

only). It is best to leave this adapter in at all times as it protects the plastic threads of the

antenna itself. Screw the bottom of the adapter onto a range pole, tribrach, tripod or other

equivalent mount. Attach coaxial cable from the antenna connector to the antenna port on

your receiver.

Caution: Over tightening the metal adaptor into the plastic baseplate will damage

the baseplate.

The maximum directivity at 90° elevation angle (antenna boresight) is typically 8 to 10

Decibels (dB). This is on average 5 dB more than a typical patch antenna. In addition

the pattern roll-off from boresight to antenna horizon (0° elevation angle) is in the order

of 15 to 20 dB. This roll-off compares well to a patch antenna roll-off mounted on a

large choke ring ground plane. This antenna has a major advantage above the choke ring

ground plane antenna – it is lighter by several pounds and much smaller.

There is no difference in phase center location between the L1 and L2 channels. This is a

very important feature of the antenna. Base stations with very long GPS baselines

normally use a choke ring type antenna that has a physical vertical offset (z-axis) between

the L1 and L2 channels in the order of 20 mm. The vertical phase center offset then has

to be corrected because the choke ring antenna sees a different GPS/GLONASS satellite

constellation. The GPS-600-G then is very suitable for long baseline applications such as

tectonic plate movement monitoring or telescope alignment. The phase center in the x

and y-axis is located in the center of the antenna for all four channels due to its inherent

symmetry and co-centric type design.
