1. Description/Purpose
The MYTE (SCC-002) device is a radio transmitter module that creates the radio frequency (RF) signals
to relay small packets of data to the Globalstar Simplex Data Service satellite network. The MYTE serves
as a communication gateway in an embedded application to send transmit-only (simplex) data. Data
packets are in small, 9-byte segments. The MYTE supports 9, 18, 27 or 36-byte data payloads. The
Globalstar Simplex Data Service comprises a set of low-earth-orbit (LEO) satellites operating as bent-
pipe data relay devices to ground earth data collection points. This specification stipulates the operational
and physical requirements for the MYTE transmitter device that is compatible with this satellite network
system.
The MYTE device is the radio transmitter only and its integration must follow the follow basic
guidelines/limitations.
1. The MYTE must be fully integrated into a larger OEM installation/application device to provide utility.
2. The OEM integrator is responsible for ensuring that the end-user has no manual instructions to
remove or install module.
3. The module is limited to installation in mobile or fixed applications.
This specification provides the physical, electrical and integration requirements to enable application
development.
The purpose of this document is to provide some notes on basic device integration for the MYTE
transmitter module.
2. Scope
This User/Integrators Guide applies only to the Geoforce MYTE transmitter.

4. MYTE Device Overview
The MYTE device is a radio transmitter module that contains the functionality to accept configuration and
data from a host application and convey data to the Globalstar Simplex Data Service satellite system.
FIGURE 1: MYTE APPROXIMATE SIZE
4.1. Satellite Messaging Method
The MYTE device manages all the required messaging to be compliant to the Globalstar Simplex Data
Service. The application interface need only configure the device once and send data to the MYTE
using the I2C serial interface. The MYTE will queue the data to be sent and manage the process of
transmitting the data to the satellite system.
Because the messages are transmitted unsolicited and without the benefit of a two-way data link
with the satellite system, each message is transmitted several times with a random delay component
between transmits of roughly 7±2 minutes. Recommended configuration setting transmits each
message three times with time delays between each transmission to allow for the satellite
constellation to shift in position. The configuration parameters of the MYTE allow for adjustment of
number of transmissions and time delays between transmissions. This overview is provided to briefly
demonstrate how the MYTE functions in order for application developers to understand how the
simplex system operates. Integrators should know that sending a message for transmit may
therefore take up to 20 minutes to complete the transmit sequence. This does not mean that system
latency is typically that long, but because the MYTE has no way to discern if the message was
successful on first or subsequent attempts, it will repeat the message transmit per configuration
setting. The satellite system will deliver the first received message captured, typically the first
message and thus the probabilistic system latency is seconds, not minutes. Nevertheless, on rare
occasions the system may miss the first message and the data packet will have a new chance for
packet delivery success on subsequent trials.

5. On-Air Interface
The MYTE transmits data in a radio format compatible with the Globalstar Simplex Data Service. This
section provides a brief overview of the operation of the network service. Greater detail can be found in
the requirements definitions set forth by Globalstar.
5.1. RF Modulation
The MYTE transmits data using Direct Sequence Spread Spectrum (DSSS) carrier with a Binary Phase
Shift Keyed (BPSK) data modulation. The MYTE can be configured to send data on one of four radio
center frequencies. Globalstar operational requirements for channel usage must be observed by
application developers. Generally, channel A is used for North American operations except where the
device is in proximity of Radio Astronomy Sites (RAS), where channel C is prescribed. Use in other global
regions uses channel C. The channels are specified as:
RF Channel
Channel A = 1611.25 MHz center frequency
Channel B = 1613.75 MHz center frequency
Channel C = 1616.25 MHz center frequency
Channel D = 1618.75 MHz center frequency

6. Integration Guidelines
Integrating the MYTE into an application requires compliance with the network operation guidelines as
set forth by Globalstar. This section highlights the primary guidelines and restrictions; however, users
must consult with Globalstar for any updates or changes to operation that govern use of the Simplex
Satellite service.
6.1. Mechanical Interface
The MYTE is a board-level module that integrates into the host application via the surface mount pads
shown below. The MYTE top-side host solder footprint is shown below.
FIGURE 2: MYTE HOST FOOTPRINT (TOP SIDE VIEW)
Module height is 100 mils. All dimensions in mils (thousandths of an inch).
The MYTE is an RF module assembly. Therefore, care should be taken in application design to ensure
the power and data signals are electrically clean. Running RF or digital signals under the MYTE module
is not advised. It is preferred to provide a solid ground plane on the top layer of the application board
layout.

sweep time of <100msec, and trace configured for maximum hold. The application processor shall
command the MYTE transmitter to transmit a 9-byte packet on Channel A via the I2C interface. The
power measured by the spectrum analyzer at the center frequency shall be between +18dBm and
+20dBm minus the known cabling losses.
The spectrum analyzer resolution and video bandwidths shall be then set to 100kHz, the maximum trace
hold reset. The application processor on the host board will then instruct the MYTE transmitter to
transmit another 9-byte packet on Channel A via the I2C interface. The primary band average power
shall be averaged from 1.610625GHz to 1.611875GHz and the sideband powers averaged from
1.609188GHz to 1.609812GHz and from 1.612688GHz to 1.613312GHz. Both averaged sideband powers
shall be at least 20dB lower than the average primary band power.
6.2.7. Composite System Production Test
Production testing of end products incorporating the MYTE transmitter module shall be verified to comply
with relevant emissions standards by measurement of the radiated spectrum over the duration of a
transmit event. A spectrum analyzer capable of measuring a 1.61125GHz signal with 100kHz bandwidth
shall be connected to a receiving antenna through a low-loss coaxial cable. The receiving antenna shall
be nominal 50Ohm LHCP ceramic patch type with center frequency of 1615MHz±10MHZ, 1dB BW >=
25MHz, A/R 3dB Max, Gain of 3dBi min to 5dBi max at zenith. The antenna shall be positioned about
200cm above the production device under test such that the zenith of both transmit and receive antennas
are pointed directly at one another.
The spectrum analyzer shall be configured for a center frequency of 1.61125GHz, span of 10MHz, average
detector, reference level of +10dBm, range of 100dB, resolution and video bandwidths of 100kHz, sweep
time of <100msec, and trace configured for maximum hold. The application processor shall command
the MYTE transmitter to transmit a 9-byte packet on Channel A via the I2C interface. The primary band
average power shall be averaged from 1.610625GHz to 1.611875GHz and the sideband powers averaged
from 1.609188GHz to 1.609812GHz and from 1.612688GHz to 1.613312GHz. Both averaged sideband

6.3. Regulatory Certifications and MYTE Labeling
The application that incorporates the MYTE device must be properly certified for the region of operation.
MYTE will carry modular certifications for FCC, IC. In addition, the MYTE has completed EN 301-441
radio testing for potential use in the EU. These test results may be obtained from Geoforce, Inc. The
integrator however must secure operational certifications and testing of the final integrated product in
compliance with regional regulatory restrictions including the required marking of the end device.
Modular Certification Restrictions:
• The MYTE is authorized only for mobile devices. Installation in portable devices is not permissible.
• The MYTE must be installed in such a way as to prevent approach within 20 cm of the transmitting
antenna. Integrators must ensure that the product user’s manual includes the standard 20 cm
warning to end users.
• The MYTE may not be collocated with any other transmitter.
6.3.1. MYTE Device Labeling
The MYTE device (Model SCC-002) is marked with the FCC ID and IC certification number as shown
below.
FIGURE 8: MYTE LABEL
Actual size of the label is 0.500” x 0.4375”
6.3.2. MYTE Serialization and ESN Coding
Each MYTE transmitter label will also contain a Micro-QR barcode and human readable Electronic Serial
Number (ESN). The left-most digit in the labeled ESN is the manufacture ID, so as shown above, the
ESN is 2-3000000. The ESN notation is decimal, with the Manufacture ID weighted as 2^23. The formula
below provides the conversion for the ESN labeling to hexadecimal notation used in ESN reads from the
MYTE.
ESNhex = (MFG_ID * 2^23) + ESNdec
For the example label above:
ESNhex = 0x012DC6C0 = (2 * 2^23) + 3000000

pertains should be identified. Suppliers of radio apparatus shall provide notices and user information in
both English and French.
Under Industry Canada regulations, this radio transmitter may only
operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce
potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropically
radiated power (EIRP) is not more than that necessary for
successful communication.
Conformément à la réglementation d'Industrie Canada, le présent
émetteur radio peut fonctionner avec une antenne d'un type et d'un
gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie
Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut
choisir le type d'antenne et son gain de sorte que la puissance
isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication satisfaisante.
The above notice may be affixed to the device instead of displayed in the user manual.
User manuals for transmitters equipped with detachable antennas shall also contain the following notice
in a conspicuous location:
This radio transmitter (identify the device by certification
number, or model number if Category II) has been approved by
Industry Canada to operate with the antenna types listed below with
