The Garmin(R) GPS 35 TracPak is a complete GPS receiver and embedded antenna designed for a broad spectrum of OEM (Original Equipment Manufacturers) system applications. Based on the proven technology found in other Garmin 12Â-channel GPS receivers, the GPS 35 will track up to twelve satellites at a time while providing one-second navigation updates and low power consumption. Its far-reaching capability meets the sensitivity requirements of land navigation as well as the dynamics requirements of high-performance aircraft: The GPS 35 TracPak design utilizes the latest technology and high-level circuit integration to achieve superior performance while minimizing space and power requirements. Utilizing Garmin's own proprietary chipset, all critical components of the system including the RF/IF receiver hardware and the digital baseband are designed and manufactured by Garmin to ensure outstanding quality and capability: The GPS 35 TracPak is housed in a black, water-resistant case and designed to withstand rugged operating conditions. While the GPS 35 TracPak is designed as a "plug 'n play" GPS solution, the minimum system must provide a source of power and a clear view of the GPS satellites. The system may communicate with the GPS 35 via two RS-232 compatible bi-directional communication channels. Internal memory backup allows the GPS 35 to retain critical data such as satellite orbital parameters, last position, date, and time: Basic Features. Additional 8 foot power cable extension from the DB-9 connector terminates in a cigarette lighter plug for easy application of power supply voltage between 6 and 40 VDC. Asynchronous serial data interface via a single serial port with true RS-232 voltage level output. Attached 10 foot power/data cable with female DB-9 serial connection, ready to attach to your PC. GPS35PC does not implement Port 2.
