Digital Multiplex transponder for all your communication needs

DMT deployed in GEO orbit for round the clock coverage providing reliable error free data.

  • There is presently no operational digital multiplexed transponder of any significant capability available for deployment in GEO – nothing even close
  • Analog Repeaters have Serious Shortcomings and are prone to attacks.
Product Specification:
  • Xilinx Zynq Ultrascale+ device with 2 ARM A53 64-bit cores and 2 ARM R5 32-bit lockstep cores.
  • 200K - 500K logic elements.
  • 17.6 - 26.5 Bits of Block RAM, and 900 – 2020 DSP Slices (36 x 36-bit multipliers).
  • AD9371 radio board
  • DVB-S2 QPSK AND FEC rates from ¼ to 8/9 will be supported at symbol rates from 80kHz to 8MHz (RF output of 100kHz to 10MHz
  • Compliant with Next Generation CubeSat Bus (NGCB) and 6U CubeSat Design Specification Rev 1.0
  • BBP will provide 4 to 8 pairs of high speed SERDES channels capable of JESD204B operation at rates up to 12.5 GHz.
  • Primary downlink : 10.45 – 10.50 GHz.
  • Primary uplink : 5.65 GHz. Primary control uplink : 1.260 – 1.270 GHz
  • Scalable upto: a 24 GHz downlink and 10.45 uplink.

Application In Space Domain

    Space to Space communication : Satellites need to talk to create a mesh topology. Data received from a space to space uplink will be multiplexed onto the aggregate downlink in the same manner as the high-data rate earth to space links.

    Host Data generated in the space : Host data consists of data that originates within the host platform. This can include telemetry or data that is related to the mission, e.g. images, scientific or educational data.

Application in Autonomous Vehicle domain:

  • Connected Autonomous Vehicles with seamless transition from 4G - 5G: Vehicles are expected to leverage hybrid connectivity (cellular and satellite) and automatically switch to the most convenient network by ensuring coverage in every situation to provide ubiquitous connectivity.
  • IoT for connected devices on field monitoring and connected vehicles :In this context, connected devices need to be adopted to monitor, alert, and respond. Common satellite communication link will help to share this data among connected vehicles.
  • Real-time hazard warning:This use case relates to an autonomous vehicle receiving information relevant for the road/route ahead that require to increase driver awareness or reduce reliance on automated vehicle features like lane keeping. The connectivity with the Geo satellite which has a wider coverage of earth will help to convey this information.
