SATCOM modules are indigenous designs based on our SDR chipsets. We provide a both L and S band MSS terminals, broadcast dongles and transceivers. These are low power, small factor modules supporting a slew of sat-com waveforms. These products currently work with ISRO (Indian Space Research Organization) satellites. Based on customer requests, the modules can be reprogrammed to support specific waveforms and satellites

Satellite S - Band Systems

SAMRAT is a two-way, S-Band Satellite Mobile Radio Terminal device, that can augment an Android Smart Phone into a Satellite Phone. Designed to operate over ISRO’s GSAT satellite network, SAMRAT supports voice, data short messaging and geo location services.
SAMRAT can be connected to any 5.5-inch COTS Android Smartphone, either through an OTG USB cable (wired) or via Bluetooth (wireless). Once the device is connected to the smartphone, it is registered in an android application. The app enables registration, authentication, and access to contacts and phone dialer. It provides the functionality of making and receiving calls from PSTN/Mobile/Satellite phone, and short message service.

Benefits

  • SatSleeve to fit a 5.5” COTS Android phone
  • Compact, Light weight and low power consumption
  • Offers excellent connectivity in no mobile network coverage areas
  • Capable of Voice / SMS / Data communication
  • Highly Secure mode of communication
  • Software programmable to support any other hub waveform

NAVDOOT is a two-way Moblie Satellite Service terminal deployed for tracking of vessels and fishing trawlers in the deep sea.

NAVDOOT comprises of a S-Band modem, GPS receiver (upgradable to IRNSS-NAVIC), Bluetooth module, Antenna and Battery all housed inside a ruggedized IP67 casing providing excellent water and dust protection. The built-in battery, enclosed within the casing, lasts for a day.

Navdoot can be paired with any Android phone over a bluetooth link. An android APK is used for control, configuring and interacting with the device. The application enables the user to send text messages to the central hub. Similarly, the application can receive any text messages either broadcasted by the hub or directed specifically to the terminal.

Benefits

  • Reliable two-way communication in deep sea
  • Emergency broadcast communication to all vessels
  • Ability to send SOS signal from boat during emergency
  • Location tracking of vessels in deep sea
  • Fishermen get alert of bad weather
  • Information of Potential Fishing Zones to fishermen

NAVRAIL is a Two-way Mobile Satellite Service terminal for real-time tracking of locomotives. It is designed to enable Real Time Information System (RTIS) of Indian Railways. It has S-band modem and GPS modules, transmitting geo-location coordinates and other data to remote HUB through ISRO’s GSAT satellite. The RTIS will enable users to track the live location of the locomotive using a specially designed app and website.

NAVRAIL works on dynamic TDMA mode with continuous receive and burst transmit option. The transmission bursts could be as small as 200 ms and transmission boundary conditions are ensured with in-built GPS used for time synchronizing across terminals.

NAVRAIL is capable of IESS waveform reception at 9.6/16/32 kbps data rates and supports programmable, fixed and variable length Burst transmission rates of 1.2/2.4/4.8/9.6 kbps in BPSK/QPSK modes of transmission.

Benefits

  • Easy real time locomotive location tracking
  • Emergency broadcast communication to locomotives
  • Reliable Hub-to-Locomotive and Locomotive-to-Hub communication
  • Better management of locomotive movement
  • Real time information about train arrivals and delays
  • Data Analytics for locomotive management
  • Provision to report locomotive diagnostic information
