Refer to the Sapphire Technical Reference Manual,
Appendix E, for RTK operation information.
For IGS or similar permanent Base applications,
NavCom offers a Choke Ring antenna option to
significantly reduce multipath errors on signal
reception.
 NTRIP Support
The generation of differential GPS correction data is
usually done directly on the GPS receiver of a
reference station, but this data can also be derived
from observations obtained by networked reference
stations. The combined data stream is then fed into a
network computer and made available on the
Internet.
Refer to Appendix E, RTCM Internet Protocol
(NTRIP).
Also see the [NTRIPCLIENT], [NTRIPCONFIG], and
[NTRIPSERVER] commands in the Sapphire
Technical Reference Manual for detailed instructions.
 GNSS Performance
The SF-3050 utilizes
NavCom‟s Sapphire GNSS
engine, which incorporates several patented
innovations. Sapphire
‟s industry leading receiver
sensitivity provides more than 50% signal to noise
ratio advantage over competing technologies. This
results in improved real time positioning, proven
through independent tests, when facing various
multipath environments.
