Abstract
Abstract An Adaptive Position Transmission Algorithm (APTA) for mobile radio device where position information is required, using any transmission medium such as high frequency (HF), very high frequency (VHF), ultra high frequency (UHF), Satellite Communications (SATCOM), etc. A mobile radio device employing the APTA provides accurate and automatic position reporting and thus, in a tactical environment improves situation awareness and reduces the probability of fratricide. A mobile radio device employing the APTA also reduces the number of options available to the user thereby simplifying the operation thereof while improving overall performance in most applications. The APTA accomplishes this by monitoring position, time and radio network parameters to determine when stand alone messages will be transmitted. The APTA factors radio network loading with movement and periodic thresholds. As radio network loading increases, the movement and periodic thresholds are increased to reduce the impact of position reporting on the radio network. The APTA also incorporates a time limit which prevents the radio from transmitting too often. This time limit is based on radio network loading.
