Overview The Tractus Datalogger is a rugged GPS data logger with the unique feature of wireless download capability. One of the mayor draw backs of other dataloggers in the market is the need to extract the information from the vehicles using cables connected to a computer or hand-held terminal; this is both time consuming and becomes a maintenance burden as your fleet grows. Using the Tractus Datalogger and a low cost radio base installation, the download of the information can be accomplished when the vehicles are in your yard resting or between service calls. The download process is fully automated using the Tractus Manager software, running on a PC. Tractus Manager is also a route analysis tool and can generate a number of reports for fleet control, tracking and maintenance. Radio communication between your base station and your vehicle is accomplished using a no-license FCC registered spread spectrum transceiver operating in the ISM band. Once a vehicle is detected by the base station, the download procedure begins.

The logged GPS data can contain Position, Velocity, Altitude and the logical events detected by the five inputs of the Tractus Datalogger; these logical inputs can be associated with user defined events. Up to 100,000 points and events can be logged and special filters can be programmed if you need to optimize the information and download times. Features Tractus GPS datalogger Wireless download interface (902-928 MHz Frequency Hopping Spread Spectrum radio, up to 500m, line-of-sight) No radio license required Five digital inputs for user-defined, event logging Up to 100,000 log points (position, velocity and altitude) Non-volatile storage Optimized storage using programmable filters (satellites in view, time, distance and speed) Uses Industry standard Sirf Protocol Power: 12VDC GPS Unit: Type: Frequency L1, 12 channels (satellites). Positioning Exactitude: 5m, without Selective Availability; 21m with Selective Availability; 2m with Differential GPS and without Selective Availability. Exactitude is measured using the Circular Error Probability calculation. Acquisition signal time (typical): Cold Start: 60 seg. Warm Start: 45 seg. Hot Start: 2-6 seg. Re-acquiaition: 100ms. Operational limits: Altitude: 60,000 ft (18,300 m) Velocity: 1,000 Kn (1,852 Km/h) Acceleration: 4g.   Tractus Manager Software Up to 1600 vehicles per site Used to wireless configure Tractus GPS Datalogger parameters Information Catalogs: Vehicles Interest point types (point-of-sale, customer's address, school zones, etc.) Points of interest Delivery routes Safe transit zones Maintenance plans Download polling schedules Reports: Per vehicle alarm notifications (violation to predefined speed limit; excess travelled distance; excess of dead-times) Out of route vehicles Out of map vehicles Vehicles required for maintenance Transit time per route Travelled distance per route Download Tractus brochure (30.3KB)
