Description

110/112
GPS L1/L2 & Fugro SeaSTAR SGG
SGG accuracy < 1 m
SBAS accuracy < 1-2 m
IALA accuracy < 1-3 m
DPS 110 utilizes SeaSTAR SGG service capable of world wide sub-metre accuracy. DPS 112 utilizes in addition GLONASS L1/L2.
132
GPS L1/L2 & SBAS receiver
GPS accuracy < 2 m
SBAS accuracy < 1-2 m
DGPS accuracy < 0.5 m
Seastar XP hor. acc. 0.1 m
Seastar XP ver. acc. 0.15m
Has a combined dual-frequency GPS and SBAS receiver. This enables the system to both compensate for errors introduced by high ionospheric activity and utilise the free of charge SBAS corrections. Perfect system in the outskirts of the SBAS coverage areas. Utilizes Seastar XP correction service giving accuracy on decimetre level.

XP2/G2 hor. acc. 0.1 m
XP2/G2 ver. acc. 0.15m
DPS Engine comprises an 'All in One' signal processing core with advanced algorithms and true parallel processing of all available signals including SBAS (e.g. WAAS, EGNOS, MSAS). DGNSS corrections from different sources are combined by the unique MULTIREF capability. Ability to utilize XP2/G2 correction service giving accuracy on decimetre level.
432
GPS L1/L2/L5, GLONASS L1/L2, Beidou B1/B2, Galileo E1/E5 & SBAS receiver
GNSS accuracy < 2 m
SBAS accuracy < 1-2 m
DGNSS accuracy < 0.5 m
XP2/G4 hor. acc. 0.1 m
XP2/G4 ver. acc. 0.15m
DPS Engine comprises an 'All in One' signal processing core with advanced algorithms and true parallel processing of all available signals including SBAS (e.g. WAAS, EGNOS, MSAS). DGPS, DGLONASS, Galileo and Beidou corrections from different sources are combined by the unique MULTIREF capability. Ability to utilize high precision correction services, giving accuracy on decimetre level.
4D
GPS/GLONASS L1/L2 & SBAS receiver
RTK accuracy 1 cm + 1.6 ppm RMS
High precision accuracy 0.1 m
DGNSS accuracy < 1 m
SBAS accuracy < 1 m
Roll/Pitch acc. 0.01 RMS
Inertial aided GNSS Solution. DPS 4D combines the latest achievements in advanced GPS and GLONASS technology aided by a high performance IMU (Inertial Measurement Unit). DPS 4D effectively combats common mode errors occasionally observed when using two or more GNSS based systems.
5D
GPS/GLONASS L1/L2 & SBAS receiver
RTK accuracy 1 cm + 1.6 ppm RMS
High precision accuracy 0.1 m
DGNSS accuracy < 1 m
SBAS accuracy < 1 m
Roll/Pitch acc. 0.01 RMS
DPS 5D provides a superior solution to the most challenging installations. The unmatched all-in-one package addresses the extremes of accuracy and reliability. In addition to providing precise positioning, DPS 5D also offers precise GNSS based heading. The dual GNSS receiver solution together with the INS integration ensures a continuous position solution by bridg­ing gaps in the GNSS reception and increasing position stabil­ity in periods with limited GNSS availability due to masking, scintillation and interference.
