Description:

GPS+SBAS Solution
The DG14™ from Magellan is a cost-effective, sub-meter GPS+Beacon+SBAS receiver. It incorporates signals from Satellite Based Augmentation Systems (SBAS), such as WAAS, EGNOS & MSAS, or an embedded beacon receiver to provide sub-meter differential positioning.

The DG14 comes standard as a 14-channel receiver with 12 GPS L1 code and carrier channels and two SBAS channels. Two additional DGPS beacon channels are available as an optional feature. The two SBAS channels can be configured as two additional GPS channels offering a total of 14 GPS channels. DG14 can provide up to 20-Hz precise three-dimensional position and raw data for real-time guidance and navigation.

DG14 can output SBAS ranging, ephemeris and differential corrections through the serial port. While DG14 offers three standard RS232 ports, it is capable of single port operation. In addition, DG14 comes standard with User Defined Messages (UDM) software, a feature that enables the user to create custom messages.

DG14 incorporates Receiver Autonomous Integrity Monitoring (RAIM) that allows the receiver to detect and correct errors in the satellite signals. In addition, the DG14 features Horizontal Protection Level (HPL) output for aviation applications such as Automatic Dependent Surveillance Broadcast (ADS-B) stations. It also features improved in-band and out-of-band interference rejection capabilities. For best performance, DG14 can be configured to use a Kalman filter with adaptive dynamic mode or user can select dynamic modes such as walking, ship, aircraft, etc. to match the operating conditions.

New RTK Engine
The DG14 receiver now supports RTK positioning with reliable decimeter to centimeter accuracy. The DG14 allows customers to choose from fixed centimeter solutions or fast decimeter solutions with the new state-of-the-art Blade technology. In addition, the DG14 supports moving base operation and heading plus pitch/roll computation with auto-calibration for easy initialization. For best results, the DG14 rover can be configured to use SBAS signals in addition to GPS for RTK positioning with RTCM 3.0-compatible base station.

WADGPS Processing with (M) Option
The DG14 WADGPS algorithm has been developed by Magellan to provide a position solution using corrections coming from a network of up to 24 base stations. The DG14 WADGPS algorithm has been extensively tested in operational conditions in various environments: North-Sea, Equatorial region and Southern Hemisphere, and has shown excellent results over medium-spaced (1500 km) network, even during ionospherically active days.

Integrated Differential Optimization (IDO)
With the IDO, you can choose either a single or multiple sources of corrections from up to seven sources/channels of corrections (serial port, SBAS, and beacon). Sources are selected in order of preference through a Primary-Secondary scenario mode or combined using a Multi-Base processing, automatically or manually.

Multipath Mitigation
Multipath is the single largest cause of differential GPS position errors. The Strobe Correlator (patent pending) is a digital signal processing technique implemented in the hardware and software of the DG14 receiver that removes multipath errors almost entirely for reflected signals with delays of 37 m or more. This represents the best DGPS multipath mitigation available today in GPS receivers - and it is available standard with the DG14.

Evaluation Software
Ashtech EvaluateTM software is available with the DG14 and provides visual displays of satellite information such as SNR, receiver position and velocity as well as data logging and analysis. It also enables direct communication with the receiver. Compatible with all Ashtech receivers, the software runs on Windows version 3.x Windows 95/98 and Windows NT platforms.
