GNSS RTK Receiver

with Calibration-Free Tilt Compensation

GNSS RTK Receiver with Calibra�on-Free
Tilt Compensa�on

Empowered by a high precision iner�al measurement unit

(IMU) on Ul�mate version, Oscar GNSS receiver from Tersus is
a new genera�on of �lt survey GNSS receiver. This kind of
calibra�on-free �lt compensa�on is immune to magne�c
disturbances. Oscar gives a surveyor unprecedented flexibility and
efficiency — holding the survey pole upright is no longer necessary.
With an internal high-performance mul�-constella�on and mul�-
frequency GNSS board, the Oscar GNSS Receiver can provide
high accuracy and stable signal detec�on.

The built-in high-performance antenna can speed up the �me

to first fix (TTFF) and improve an�-jamming performance. With
a Nano-SIM card inserted in Oscar, it can access Internet,
transmit and receive correc�on data through 4G/WiFi network.
The built-in UHF radio module supports long distance commu-
nica�on. The built-in large capacity ba�ery is detachable and can
display power level. Two ba�eries support up to 16 hours of
fieldwork in 4G/3G/2G network and Rover radio mode. Oscar
can be easily configured with 1.54 inch interac�ve screen on
Ul�mate and Advanced versions. The rugged housing protects
the equipment from harsh environments.

Customers also have an easy backup from Tersus Caster Server

(TCS), so that a GNSS BASE sta�on can be quickly set up to
broadcast correc�on stream via mobile networks instead of
radio. Na�vely supported by FieldGenius and Nuwa App, Oscar
can be configured to different work modes to suit various daily
jobs. Also pillared by the prompt technical supports from Tersus'
global partner network, Oscar GNSS receiver is a surveyor's
capable and reliable workmate.
