GPSFlight, the leader in high-performance, miniature wireless GPS telemetry, is pleased to announce the delivery of the ST900, the next generation long range telemetry transmitter. The ST900 delivers new levels of performance and greater system integration capabilities than other devices in its class.

The ST900 telemetry transmitter features include:

  •     Small form factor 75mm x 52mm x 20mm for a multitude of mounting options
  •     50 Channel WAAS GPS with fast first time to fix generally less than 29 seconds
  •     -160 db GPS sensitivity for indoor coverage (in many cases)
  •     Long battery life - runs more the 12 hours on 4 AA batteries
  •     Input Voltage from 4VDC to 12VDC
  •     Integrated 17 bit temperature compensated digital altimeter
  •     Programming wizard software simplifies field firmware updates, and programming of large groups of units

GPSFlight customer John McAtee, uses the ST900 to track experimental sounding rocket flights in order to see real-time performance while the vehicle is in flight, and to aid in recovery. John was one of the first to use the ST900 for such a difficult tracking task. "This thing rocks!" says John. "The ST900 outperformed my expectations, providing real-time data on a rocket flight subject to high G-forces."

Craig Kairis, CEO of GPSFlight, was extremely pleased with the ST900's performance in this dynamic test, which Mr. Kairis says is much more extreme than most customers. "We spent lots of time talking to our customers about what they needed in this next generation transmitter" says Mr. Kairis. "Using cutting edge components such as the uBlox 5 chipset enables low power, but very high performance GPS tracking, and this combined with our CPU creates delivers incredible performance in such a small, yet reliable and inexpensive package."
