STXe - The Intelligent GPS Telemetry Platform (New Version 2.1)

Overview:
The STXe telemetry modules have several very powerful enhancements thanks to a powerful onboard computer and new  TracID technology.  With TracID, each transmitter has its own separate ID, and can transmit information during the same second as other units, and with the GPS-TEAM software, multiple units can be tracked on the PC screen -- all at once. 

The GPSFlight TracID CPU multiplexes data from GPS and other devices into a highly compressed  binary packet which is synchronized with other transmitters using the 1 microsecond accuracy of the GPS satellite signals.  Each transmitter is programmed to a particular TracID channel, and given a 3 letter name so it can be identified uniquely.

The module size is only 2.9"x1.9"x1.2" deep, and runs on 4 x AA or AAA battery power.  The picture below shows the STXe Telemetry Platform with the Radio module removed.

The following are key features:

Packetized Data Stream
Position information is sent from the TracID enabled GPSFlight unit to the ground using a proprietary, highly compressed data stream.  This data stream converts information from the GPS NMEA output into very small packets of position information, and names each packet so it can be identified on the PC.  This enables tracking of multiple units simultaneously with one base station.  This data stream is approximately 1/100th the size of the standard NMEA data.  As a result of the compression, the system can track 10 transmitters per second.

Expansion Ports
The TracID enabled boards like the STXe support some expansion options not found in other modules.  The 'Feature port' allows addition of external devices such as:

• Pressure

• Voltage

• Temperature

• Remote triggering of events based on position

• Panic event registration

• Other custom inputs such as RPM, etc.

Indicator LED
The onboard CPU provides an indicator LED which shows GPS lock status visually without having to look at the PC.  The light flashes red every 3 seconds when no lock is present.  It flashes orange every second when 2D lock is available, and it flashes green every 3 seconds when 3D lock is available.

Board Voltage Indicator
The onboard CPU also sends board voltage information to the RXBase station so the user can keep track of remaining battery run time.

Internal/External Antenna
The STXe comes with an high gain wire transmitter antenna and connector for a GPS antenna.  This configuration allows for the use of a variety of GPS antennas, depending on the application.  The picture below shows the STXe with the radio and a GPSFlight 4" lead patch antenna - available as an option.
