Satphone Direction Finding (DF)

Satphones pose problems for militaries and law enforcement agencies who seek to use COMINT techniques to geo-locate SATCOM users. TDMA (Time-Division Multiple Access), a channel access scheme used by many SATCOM systems allows several users to share the same frequency channel by dividing it into different time-slots. Geolocating these can become very difficult when multiple satphones are in the field-of-view, especially with basic Direction Finding (DF) algorithms. CommsAudit provides portable, mobile and fixed solutions that can be tailored to your CONOP to maximise the probability of intercepting satphone SOIs.
