North Star - Low Profile D-cell collar
The Low Profile D-cell collar, priced starting at $700 USD, is a significant innovation in tracking technology, offering robust GPS functionalities with a specified accuracy of 2.5 meters CEP and 5 meters SEP. Circular Error Probability (CEP) indicates the radius of a horizontal circle where 50% of the fixes will be contained, while Spherical Error Probability (SEP) measures the radius of a sphere that encapsulates 50% of the fixes. The collar features a unique operational protocol where the GPS engine is disabled after five consecutive positions (collected at one per second) are attained with horizontal accuracy of 5 meters or less, optimizing battery life and performance. With its advanced design tailored for low-profile applications, this collar is particularly useful for a variety of wildlife tracking and research initiatives. Coupled with the efficient NSG-LD1 Component ensuring extended battery life expectancy and precise antenna weights with Rexolite cover, this device is pivotal for professionals in ecological studies and animal behavior research.

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.
