Description The GSatSolar/GSatRancher is a Satellite transmitter designed to send GPS location data to a network of low earth orbiting (LEO) satellites. The received data is then delivered to a telematics platform or other processor to visualize and utilize the data. The GSatSolar/GSatRancher is powered by a battery. The GSatSolar/GSatRancher features a solar charging circuit that allows battery charging from the built in solar panel.
GSatSolar Best Performance The GSatSolar/GSatRancher determines its location by triangulation of GPS satellites, and then transmits the location back to a communications satellite. It is important to understand the application and importance of good satellite coverage, outdoor locations, and take into account obstructions, buildings, and metal objects that greatly affect the antenna performance. These devices are transmitting a signal up to 1,000 miles.
GSatSolar Mounting Options Clip The clip can be mounted to a surface with ● Screws ● Strap ● VHB ● Adhesive To attach, press the GSatSolar/GSatRancher into the clip until you hear a firm snap on both sides. To detach, use the indent in the clip arms to release one side of the GSatSolar/GSatRancher, then release the other side. NOTE: The clip is designed to hold the GSatSolar/GSatRancher very firmly. It will take significant force to remove the GSatSolar/GSatRancher.
GSatRancher Mounting Options Ear Tag NOTE: The Crimping Tool is not included with the Ear Tag kit. The crimping tool (Allflex Universal Total Tagger or compatible) can be purchased locally or via online shops readily. NOTE: The Male Pin is not included with the Ear Tag kit. The male pin can be used from any compatible tag and is considered consumable. To move the tag between animals, cut the male pin and replace it with a new male pin. Components of the ear tag 1. 2. 3.
4. The tag should be placed vertically, in the middle of the ear, between the two cartilage ribs and 2/3 from the outside edge of the ear, 1/3 from the head. (Application too deep in the ear is not recommended). 5. The female portion of the tag should be on the outside of the ear with a tag application. Strap/Collar Insert a nylon strap through the rails on the top and bottom side of GSatRancher as shown in the diagram.
Identification Features Rear Front ID: Printed on the front of the unit is a 9 digit number. The ID advertised on Bluetooth will be this ID without the leading zeros. Rev 1.0 - 20211004 QR Code: Printed on the rear of the unit is a 9 digit QR code which represents the ID of the unit. This code can be scanned by mobile apps or any 2D scanners for quick identification.
Theory of Operation The GSatSolar/GSatRancher operates on the Globalstar LEO satellite network. LEO (Low Earth Orbit) means that there are a number of satellites in low earth orbit that constantly orbit the planet and can communicate with devices that are within range of its current position.

Functional States Over the GSatSolar’s/GSatRancher’s lifetime, it transitions through the following states. Pre Operational State Note that these states are defined by events that have occurred prior to the device becoming fully operational. ● Configuration Mode: This describes the state in which the unit is shipped. No operational profile and no lifetime have been programmed into it. The unit’s solar panel has not been uncovered and the battery has not been allowed to charge.
Tracking Modes The GSatSolar series supports 3 tracking modes, which are detailed below. Accelerometer: the GSatSolar/GSatRancher contains a built in accelerometer which can be used to detect motion to trigger position transmissions instead of a timer based transmission cycle. Standard Tracking Tracking reports are simply sent based on the defined interval between position transmissions. This mode does not use the accelerometer.
Location Transmission Behavior If the reporting interval is set to 30 minutes or greater, a redundant burst transmission will be initiated at each interval, with the number of attempts and the timing between the attempts as specified by the reporting rate. With an interval of 30 minutes or less, the GPS will retain its clock and ephemeris* data in order to perform a “hot” GPS fix. This will increase the GPS standby current to the “GPS Standby Mode” value in the table below.
Health Status Message The Health Status Message reports the current settings and condition of the device. The message generation interval is configurable from 1-30 days, with a default interval of 30 days. One message per month is generated at no charge, shorter intervals are charged according to the device plan. NOTE: One message per month minimum, cannot be set to zero. The device health check message length is 2 packets (18 bytes).
