Unit Types (click thumbnails above for details)

GPS-GSM units by Ecotone Telemetry record data and send those directly to your computer when they encounter a cell phone communications network, worldwide.

Solar units send data remotely for multiple years.
They are produced at weights as low as 13g, which enables remote monitoring of avian movements for species as light as 250g.
High efficiency equipment enables constant location recording as often as every 15 minutes.

GPS-GPRS-GSM-UHF units by e-obs record data and send those directly to your computer using telecommunications networks in a way similar to the GPS-GSM units, but with substantially more data efficiency (thousands of locations). UHF system allows direct downloading and control with hand-held system when units are nearby.

Units can "smartly" manage power and sampling, such that data are collected at very high rates when batteries are charged.
Sophisticated sampling regimes and duty cycles that respond to movement.
Solar units send extreme amounts of data for many years.
A "pinger" system allows directional tracking with VHF-like system by e-obs.

GPS-UHF sensors by e-obs and Ecotone Telemetry record data and send those to a hand-held or mounted receiver.

GPS-UHF sensors are lightweight (as low as 4.5g).
Provide energy efficiency that allows point-logging as frequently as every 5 minutes in direct sunlight, or every second on batteries.
e-obs tags record at rates of 1 point per second, and automatically "super-burst" record at high battery levels.
Collect and log up to 1 million points, which are then transmitted to a hand-held or fix-mounted receiver system across distances as great as 6km.
Constructed in a number of configurations for use on species as light as 90g, and specialized recording regimes can be programmed by the user.

GPS-GSM-UHF sensors by Ecotone Telemetry combine the benefits of telecommunications data transmission and remote hand-held data download.

GSM remote downloads.
UHF communications to facilitate data download when study subjects are not within range of a GSM network.
The sensors are available in a number of configurations and at weights as low as 17g for use on species as light as 350g.
