SkyWAN Next Generation


SkyWAN NG incorporates the new Turbo φ modem from the HEAT programme into the new SkyWAN IDU 7000 and updates SkyWAN with the latest available modem technology.

The results of the verification show, that the expectations are fulfilled and the modem shows a better performance than any other burst modem on the market.

This gives the customer:

  • A higher throughput (10 Mbit/s) in all directions,
  • Reduced outdoor unit sizing and cost, and
  • Link budget advantages,
  • Due to the best-in-class Eb/No values of the unit, together with the already known features of SkyWAN.


  • Productization of the Turbo φ modem
  • Verification and optimization of its performance,
  • Integration with SkyWAN software,
  • New Unit “SkyWAN IDU 7000”.


The customers’ benefits of SkyWAN Next Generation, and the new product IDU7000 are:

  • Higher throughput (10 Mbit/s) in transmit- and receive direction between all stations in a mesh network and in star networks,
  • Reduced outdoor unit sizing and cost, and
  • Link budget advantages due to the best-in-class Eb/No values of the unit.

together with the already known features of SkyWAN.


ND SatCom’s SkyWAN system is originally designed for mesh networks, but can serve star applications as well.

SkyWAN NG provides a number of unique features:

  • Multitude of services:
    • Telephony (analog, digital, country specific signalings and interfaces),
    • Telephony over IP, with guaranteed voice quality,
    • Realtime at low and high data rates (from process control to live TV),
    • Bit-synchronous realtime data, unicast and multicast,
    • Frame Relay user-to-network and network-to-network,
    • IP transmissions, with a built-in router, unicast, multicast, QoS, OSPF.
  • Transmission data rate up to 10 Mbit/s in all directions,
  • No blocking in the mesh network, because the connections in all directions need only one modulator and one demodulator at each site,
  • Extensibility to four demodulators (if required to upgrade a central site),
  • Highest network and services availability due to:
    • Seemless network control redundancy: no service interruption,
    • Continuous Transmission Power Control with immediate adaptation to changing atmospheric attenuation.

The complete project is subdivided into the following parts:

  1. Specification and System Architecture,
  2. Development of prototype boards,
  3. Design and implementation of programmable logic,
  4. Adaptation of software to new modem,
  5. Development of test software for the hardware tests,
  6. Verification and certifications.
