Jotron integrates STM technology with VSAT systems

VSAT antenna manufacturer Jotron has announced that it has implemented the open VSAT Antenna Control Protocol (VACP) developed by STM Group Inc, and has concluded interoperability testing with STM’s broadband satellite routers for mobile VSAT networks.

STM and Jotron have developed VACP to minimise interruptions of service during handover between satellite footprints, and to minimise the effect of blockages.

VACP is a TCP/IP based protocol that facilitates the exchange of information between an Antenna Controller Unit and a satellite router.

It allows the satellite router to command the antenna and enables the use of Automatic Beam Switching, which transfers connectivity from one satellite beam to the next as a vessel passes through multiple footprints.

In addition, VACP enables users to meet government regulations by commanding the antenna to mute the signal in no-transmit zones.

The companies say that VACP is also compatible with future beam handover requirements for Ka-band.
