I have had a few requests for a GPS addon for Teensy and it is now available on Tindie.
It fits directly on top of the Teensy, but can also be breadboarded.
Serial UART: Adjustable 4800~115200 bps (Default: 9600bps), Teensy Serial1 is used
Update Rate: 1Hz (default), up to 10Hz
Protocols: NMEA 0183, PMTK
Horizontal Position Accuracy: Autonomous <2.5m CEP
Velocity Accuracy Without Aid: < 0.1m/s
Acceleration Accuracy Without Aid: 0.1 m/s2
Timing Accuracy: 1PPS out 10ns
Reacquisition Time: <1s (Cold start acquisition approx. 35s.)
Operating Temperature: -40°C to 85°C
Storage Temperature: -45°C to 125°C
Dynamic Performance
Maximum Altitude: 18000m, * Balloon Mode up to 80km altitude *
Maximum Velocity: 515m/s
Maximum Acceleration: 4G
Power Supply 2.8V ~ 4.3V (by default 3.3V from Teensy)
Power Acquisition 18mA
Power Tracking 12mA
Other features: Anti-Jamming, Multi-tone Active Interference Canceller
Low current LEDs: right - power, left - programmable via pin 2
Overall power consumption <70mA incl. Teensy
Happy to answer any questions.
