Page 4: Introduction
The STINGR is a satellite transmitter radio module which contains a satellite transmitter, GPS receiver, motion sensor, and a dual band patch antenna. The STINGR is a surface mount module designed to attach to a user defined host PCB which must provide power and communications with a host processor which will control the operation of the STINGR. -

2.1 Theory of Operation The STINGR operates on the Globalstar LEO satellite network. LEO (Low Earth Orbit) means that there are a number of operates on the Globalstar LEO satellite network. LEO (Low Earth Orbit) means that there are a number of operates on the Globalstar LEO satellite network. - Page 6 (redundant) transmissions for each message being sent over the Globalstar network. The default value for the number of redundant sent over the Globalstar network. The default value for the number of redundant transmissions transmissions per message is 3. This means that each message sent to the STINGR STINGR will be transmitted 3 times.

USB interface, and test mode switches. Since the battery is located on the same board as the STINGR, no decoupling capacitor is required on the VBATT input, however, if there are battery leads, lengthy power distribution, or noise sources present, a suitable decoupling capacitor might be appropriate. -

Page 31: Test Modes
All test modes are activated by grounding selective pins on the STINGR prior to applying power. Once power is applied, the STINGR will sample the states of the pins and based on the states of the pins, the STINGR will enter the selected test mode. - Page 32 Revision 0.2 STINGR Users Manual The channels are selected via the Rx and RTS pins as follows Channel Channel specified in the flash setup. To specify channel A, it must be the default channel specified in the flash setup. See Setup command for details.
