North Star - D-cell Collar

FromNorth Star Science and Technology

SHARE

The D-cell Collar, starting at $700 USD, is engineered for advanced wildlife tracking and monitoring, offering robust performance with a configuration of a single D cell. It delivers an output power of 150 mW with a BPSK-modulated PRN code and operates in the frequency range of 1611.25 to 1618.75 MHz. Its GPS engine is the μBlox 16 Channel, promising horizontal accuracy within +/- 10 meters and vertical accuracy within +/- 25 meters, with data anchored to the WGS84 datum. Designed for extreme conditions, the collar functions efficiently within temperatures from -40 to +50 degrees Celsius. The VHF power output varies from 1 to 2 mW. The GPS receiver and Globalstar transmitter are integrated, making the system versatile for various wildlife applications. Battery life expectancy is approximately three years, though environmental conditions may impact this duration. The device's reliability is enhanced by turning off the GPS engine after five consecutive fixes with a horizontal accuracy of 5 meters or better. The collar is ideal for use in diverse wildlife research and conservation projects.
