SINCGARS
The Single Channel Ground and Airborne Radio System ( SINCGARS ) refers to a family of military radios for the land mobile service that are used particularly frequently within the NATO armed forces.
description
The SINCGARS standard was developed after the Vietnam War in the 1980s in order to be able to continue to offer communication services to troops even under the influence of electronic countermeasures by the enemy. In addition, eavesdropping on the connection should be prevented as effectively as possible. This is achieved on the one hand by Frequency Hopping Spread Spectrum (FHSS) and on the other hand by encryption . SINCGARS radios have a modular structure and have a wide variety of dimensions and capabilities. Only the following specifications are binding for each device:
- Frequency band : 30-87.975 MHz ( FM )
- Channel bandwidth : 25 kHz
- Frequency hops: 100 per second
These relatively free limits have led to a large number of variants, from lightweight systems for soldiers on foot to large and powerful devices for use in vehicles and aircraft. In addition to the usual radio messages, all current systems also master functions for digital data transmission; the data rate is usually in the kilobit range. In most devices, the codes for the encryption module can be entered either using a key card or a numeric keypad . A total of over half a million devices were built, so that it is widely used, especially among NATO forces, and thus facilitates communication between the individual forces of the member states.
