We have been quietly working on a new offering in wildlife tracking collars. After four years of development and testing we have a single-housing iridium collar with solar assist now offered publicly. In most ungulate deployments we are able to achieve 1 gps fix per hour with no battery decline even in winter - meaning our collars are limited to the lifespan of the components, not battery storage.
If anyone has any questions, comments, or a collar project to discuss please reach out! We are keen to learn more and serve this market. We are currently offering this collar commercially for most ungulates species in North America and searching for further test cases on carnivores.
Collar Specs: 270g Margo Luminous and 330g Heavy Duty. Available in 1" and 1.5" webbing collars. Store-on-board and remote data globally download through iridium satellite connection.
Our main innovation is the use of a single-housing design. Rather than the traditional separate battery and antenna compartments, we package all collar components in a single housing that hangs below or on the side of a mammals neck. We are able to achieve lower-weight for the same product and reduce external cable connections. A side benefit is that our collars don't need to be custom ordered by neck size - you just trim off any excess collar material.
