SATCOM modem and control panel

Installation of Latitude SkyNode Satcom and Tracking System comprises of installation of a Latitude Tecnologies’s Skynode S200 Modem in the baggafe compartment (aft RH) avionic shelf and a Northern Airborne Technologies PTA12-300 Dialer panel on the pedestal panel for the control of the system. In this installation the Latitude system uses a dual GPS/Satcom (Iridium) integrated antenna.
The Latitude SkyNode S200 provides both voice satellite communications, complete flight tracking and 2-way data networking/messaging functions, using various serial data interfaces and an integrated GPS receiver and Iridium satellite L-Band Transceiver modules. Data transmission possibilities of the S200 modem (trough 3 dedicated logic pins) give the possibility to transmit information such as “weight on wheels”, “engine running” to the ground tracking station.
The system voice communications functions are controlled in the cockpit using the NAT PTA12-300 located on pedestal panel and connected to the helicopter ICS. The Northern Airborne Technologies PTA12-300 is a compact DZUS mounted dialer with keypad and LED matrix display both featured of dimming function controlled by instrument panel illumination system. The functions of the PTA12-300 include: speech audio circuits, hook switch, ring indication, Satcom status indication, DTMF tone generation, ringer tone generation, backlighting as well as normal phone functions (e.g. hold, redial, memory).
The PTA12-300 panel has NVIS compliant backlighting and the display is filtered for NVIS radiance requirements.
