RTCM 1000-series messages. The
navigation algorithms are designed to
support single-base correction
configurations. Network adjusted RTK
formats are not currently supported.
Higher Accuracy and Reliability
With the internal radio modem and RTK options on
the SF-3040 receiver, LAND-PAK is capable of
performing centimeter-accurate RTK surveys. The
RTK algorithm developed by NavCom provides fast
initialization, and the NavCom ultra-compact binary
data format for RTK ensures robust data throughput.
The receiver can utilize NavCom RTK/UltraRTK™,
RTCM, Network RTCM, NTRIP, CMR and CMR+
data streams from other base stations to minimize
base-rover separation and allow for flexibility with pre-
existing GNSS survey systems.
GNSS Performance
The NavCom SF-3040 receivers use the NavCom
Sapphire GNSS engine. The technology is based on
NavCom’s Touchstone™ ASIC, of which more than
100,000 are in use worldwide. Incorporated are
NavCom patented interference suppression and
multipath mitigation, a 5 Hz raw data rate (up to 10
Hz
1
optional), and 5 Hz geodetic-quality positioning
(up to 10 Hz
1
optional).

RTK-Extend™
RTK-Extend™ enables continuous RTK-level
positioning accuracy during radio communication
outages by utilizing NavCom’s global StarFire™
corrections.
Traditionally, when an RTK rover loses
communication with the base station, it is unable to
continue to provide position updates for more than a
