The AT-HSDM is a cost optimised radio modem for HF/VHF/UHF mobile station use. It is extremely small (10.1 x 11.5 x 2.7 cm) and by default provides E-mail, GPS position reporting and telemetry/control functionality. The AT-HSDM is a Windows 7 (TM) based platform and provides simple customisation for a range of customer specific applications. The system is simple to install and operate.
AT-HSDM Radio Modem uses leading edge miniature PC Design along with advanced digital signal processing and modular software coding to deliver a highly versatile solution for mobile data radio networks.
The AT-HSDM Radio Data Modem contains a display driver and USB Connection – this allows a Display and Keyboard/Mouse to be connected for user input and software information. With a wide range of displays and input devices available on the market – a highly customised solution can configure for all types of mobile applications. Networking functionality via WLAN and Ethernet gives a wide range of application flexibility E.g. Email and Tactical Messaging. These can interoperate with standard computer systems such as desktop and laptop PCs using the HF/VHF/UHF radio link connected to the AT-HSDM Radio Data Modem.
