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.
