The PCM-GPS from WinSystems combines a global positioning system (GPS) receiver and a cellular modem on a single PC/104 module. The Trimble GPS interface provides position, velocity, and time information. The multiband modem supports GSM/GPRS and CDMA. An antenna connector links to an external antenna. The modem supports an AT command set along with alarm management and short message services (SMS). The 5-V board draws only 60 mA. Pricing starts at $199.
