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 Evaluate™ 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.
