General Data

Specification	Value
Output Power	150 mW
Transmit Signal Length	1.5 seconds
Temp Range	-40 to +50 Degrees Celsius
Frequency	1611.25 to 1618.75 MHz
Modulation	BPSK-modulated PRN Code
GPS Engine	μBlox 16 Channel
GPS Accuracy	+/- 10 m horizontal, +/- 25 vertical
GPS Antenna	Active
GPS Datum	WGS84
VHF Power Output	1—2 mW, 30—45 ppm
Specified accuracy is 2.5 meters CEP and 5 meters SEP. CEP is Circular Error Probability. It is the radius of a horizontal circle, centered at the true antenna position, containing 50% of the fixes. SEP is Spherical Error Probability. It is the radius of a sphere, centered at the true antenna position, containing 50% of the fixes. Note: We are turning off our GPS engine after 5 positions in a row (1 per second) are acquired with a horizontal accuracy of 5 meters or less.
