Perhaps the most ambitious platform Saankhya has developed in partnership with ISRO is an indigenous satellite phone system called Samraat. It currently works in the S-band but can also be modified to work in the lower L-band. The company claims this is the first indigenously developed satphone system that pairs with Android phones.
The Samraat module, which looks like a power bank with an antenna, can be connected to a standard Android smartphone via USB to be used as a satellite phone via an app. The company also plans to enable Bluetooth connectivity for the module so that the smartphone can be connected wirelessly to the module, which has 24 hours standby time and allows three to four hours talk time when fully charged.
The fact that Samraat, built around the Pruthvi chip, works on an indigenous system and via an Indian satellite makes it more secure than using a similar service from foreign providers.
