Examples of Operational Life
Battery life is dependent on the number of attempted GPS positions, number of Globalstar data transmissions, VHF schedule, and operational temperature. The GPS, Globalstar, and VHF schedules are all user definable in accordance with the objectives of your study. Please consult with Telonics to assist with determining what would work best for your application.
Estimates below assume average low temperatures of 0°C for extended periods and that the VHF transmitter has an average pulse period of 1500 ms (40 beats per minute). Higher temperatures will result in increased battery life and lower temperatures shorter lives. Faster VHF pulse rates or greater periods of VHF operation will decrease life. The following are examples only, with many other options possible. Each GPS fix will be transmitted at least one time in the estimates below. Battery life can be significantly extended if some of the locations (GPS or QFP) can be stored on board and without transmitting. Contact Telonics for details.

*As another example, the smallest, TGW-4065-4, configuration could provide 1 year life with 3 GPS attempts per day, a Globalstar transmission every other day, and 8 hours of VHF per week.
Considerations relative to use of the Globalstar system on wildlife:
- The Globalstar satellite network consists of 24 satellites in low-earth orbit. Overpasses provide continuous coverage over most terrestrial areas of the world, but the system is not worldwide because of its reliance on ground stations. Data received by the satellite is relayed to a ground station in real time and are available to the user within minutes. The coverage map for the Globalstar simplex system as used on wildlife is indicated by the map below.
- The Globalstar simplex system is a one-way system, thus data is retransmitted to increase the probability that the information will be received. In areas with coverage and clear views of the sky, transmission of the original message and two repeats normally results in data transfer percentages near 100%. The original message and the two repeats are typically scheduled within a 30-minute window, so user’s should select a transmission time when they think the animal is most likely to be in an area with good access to satellites (e.g. not when it would predictably be in a den or an area with dense cover).
- With Telonics GPS units, a single Globalstar message can transfer 5-6 GPS locations.
- Units may optionally be configured to collect QFP locations and store these locations on board the unit. QFP is Telonics quick fix positioning technology that obtains the data necessary to calculate a GPS position in as little as about 5 seconds. QFP locations can be obtained and stored with much less energy than traditional GPS positions; however, it not practical to transmit QFP locations via Globalstar. If recovery of the collar can be expected, some applications can benefit from collection of numerous QFP positions, which are stored-on-board for download with the collar in hand; and less frequent GPS positions which are transmitted through the Globalstar system.
- Transmissions can contain a mortality flag (which relates to whether there has been movement detected by an accelerometer within a user-defined period) and a low-voltage flag (which indicates the battery may die soon). You can receive real-time notification of mortality events via email at no additional charge.
- Activity or temperature data can be collected and stored on board, and be downloaded if the collar is recovered, but it is not normally practical to transmit activity or temperature data using Globalstar.
- Telonics GPS Globalstar units are FCC and IC certified and available for use throughout the United States and Canada with no additional licensing required for the data transfer component.
- Data is normally retrieved through a third-party, AssetLink Global, which offers the least expensive data retrieval option for users. Globalstar data retrieval rates are lower than other satellite-based systems (~$5.00/unit/month with one daily transmission).
Other Key Features
- In addition to the GPS and Globalstar portions of these units, they typically include a VHF transmitter. The VHF transmitters can be used to locate or monitor the collars from the ground or aircraft, including aiding in recovery of a collar at the end of a study.
- Users can program or reprogram Telonics GPS/Globalstar units through use of Telonics Product Programmer (TPP). TPP uses a graphical user interface, and makes it possible for users to program their own systems and simulate performance of the system prior to deployment.
- GPS/QFP collection schedules, Globalstar transmission schedules, VHF schedules, and sensor options can all be user-defined. Scheduling can be programmed to change over time (e.g. seasonal changes where monitoring might be less intensive at certain times of the year).
- Data retrieved through the Globalstar system, or downloaded from a collar in hand, are processed using Telonics Data Converter (TDC). TDC is used to convert raw data from Telonics transmitters into data reports and to display locations on Google Earth and Google Maps. You can review TDC reports in Microsoft Excel or other spreadsheet programs.
- All positions determined and sensor data collected is stored-on-board the collar, thus if the collar is able to be recovered, stored data can supplement what was transmitted through Globalstar.
- Telonics CR-2a, CR-5, or CR-7 programmable collar release mechanisms can be added to these collars.
- A Real-time clock calendar controls all timing functions and is re-synchronized with GPS time to assure high accuracy timing. All timing is programmed using Coordinated Universal Time (UTC).
- When turned off using a magnetic switch, these units consume less than 10 µA; this allows storage for extended periods with minimal impact on operational life.
- Units can be refurbished to their original condition at Telonics.

Telonics Data Converter (TDC) is used to convert raw data from Telonics transmitters into data reports and to display locations on Google Earth and Google Maps. You can review TDC reports in Microsoft Excel or other spreadsheet programs.
Telonics Product Programmer (TPP) is a powerful software tool used to program Telonics transmitters, and Telonics CR-5 and CR-7 collar release mechanisms. TPP gives you the ability to modify aspects of your Telonics GEN4 GPS and VHF transmitters including data collection and transmission intervals. TPP is designed for ease of use, with simple point-and-click navigation through the program.
The TSC-7A is a multi-use interface cable terminated with a USB A connector and a male BNC (bayonet style) connector. The cable is used to connect various Telonics products to a computer when using Telonics Product Programmer (TPP), Telonics Data Converter (TDC), or the CR-2a BCP-2 programming software. The BNC connector allows quick and easy attachment of various adapters.
Adapter, female BNC to alligator clips for use with the TSC-7A cable. This adapter is used for systems where programming/download connections are made using the antenna tip or saltwater switch buttons.
A release mechanism is often desirable on collars because it means collars can be recovered without having to recapture an animal and/or that an animal does not need to wear the collar for the remainder of its life. Telonics currently offers three microprocessor-controlled programmable release mechanisms that provide reliable release at a precise time. The CR-2a and CR-5 can be installed onto any Telonics wildlife tracking collar with a collar width of 2 inches or greater. The CR-7 is a smaller programmable release that can be installed on 1.5 inch wide Telonics collars.
