Waypoint GrafNav Lite
GrafNav Lite is a scaled-down version of Waypoint Consulting's popular
GrafNav/GrafNet™ software package that post-processes raw GPS data from
a number of GPS receiver formats. Using data collected at base and rover
stations, GrafNav Lite processes single frequency carrier phase, as well as code-only
(DGPS) data. This gives the user access to accuracies ranging from 10
cm to 5 metres depending on the processing mode selected and the GPS receiver
used. GrafNav Lite is ideal for users requiring sub-metre accuracies,
and its easy-to-use interface means new users will be processing data
in minutes.
GrafNav Lite Interface
GrafNav Lite supports the following GPS receivers:
- NovAtel (OEMV™, OEM4, OEM3, OEM2)
- Allen Osborne (TurboBinary)
- CMC /NovAtel (Superstar II, AllStar)
- Conexant (Juniper)
- CSI (DGPS MAX)
- Javad (All Models)
- Leica (MX series, SR series, System 500, System 1200, MC 1000)
- Magellan (CAR, MOB)
- NAVCOM (OEM GPS)
- NavSymm/Parthus (XR5, XR6, XR7)
- NavSys (AGR)
- Rockwell (PLRG series, NAVCOR)
- Septentrio (SBF)
- SIRF (Star II)
- Thales (Real Time, B-file, DSNP)
- Trimble (4000 series (DAT), 4000 series (RT), 5700, CMR, TSIP, Force5 (TIPY), SSx)
- U-Blox (Antaris)
- RINEX (2.0, 2.1)
- UKOOA
Features included with GrafNav Lite:
- Seamless static and kinematic processing
- Kalman Filter supporting C/A code, carrier phase and L1 Doppler data
- Float static solution
- Forward, reverse and combined solutions
- Easy-to-use graphical interface supports plotting of over 25 statistical parameters
- Data
can be exported in a number of projections, including: US State Plane,
UTM, Geographic, Lambert, Transverse Mercator, local, and ECEF.
- Fast processing!
- Up to 1 Hz data rates
- Accurate velocity determination
- Achievable
accuracies of 5 cm in static, 20 cm in kinematic using the L1 carrier
phase, and 1-5 metres using C/A code-only processing
Features included with GrafNav/GrafNet and not GrafNav Lite:
- Multi-base processing - supports up to eight base stations
- GrafNet - static network processing program that includes a network
adjustment and can be used for batch static processing
- Kinematic Ambiguity Resolution (KAR) - allows the user to achieve
centimetre results in kinematic mode
- Dual frequency processing - improves KAR reliabilities and can increase
long baseline accuracies with ionospheric processing. Also allows the
P-code to be included in Kalman Filter.
- Fixed static solution - allows the user to obtain centimetre or
even millimetre accuracies in static mode.
- Data rates greater than 1 Hz
- Occupation mode processing - improves accuracies under tree cover
- Interpolation of event marks - can be used to load camera pulse
information from a variety of GPS receivers
- Precise ephemeris - improves accuracies on long baselines
- Remote initialization - allows the user to enter the coordinates
of a known point to initialize the carrier phase ambiguities.
- Specialized input and output formats such as Leica IDEX
