Dual Frequency (or Multi-Band) RTK


We are excited to launch NS-HP-GN2 dual-frequency RTK receiver product. 

NS-HP-GN2 is GPS L1/L2C, Beidou B1I/B2I, Galileo E1/E5b, GLONASS L1/L2 capable. Some call such multi-band or L1/L2/L5 receiver, simply to win attention over the old-school way of calling it dual-frequency.  :-)

Key difference from NS-HP-GN single frequency RTK receiver are:

1. The NS-HP-GN2 hardware is GPS / Beidou / Galileo / GLONASS quad-constellation capable, while NS-HP-GN is GPS / Beidou or GPS / GLONASS dual-constellation capable. Meaning with more signals to work with, NS-HP-GN2 will have better RTK performance than NS-HP-GN.

2. NS-HP-GN2 can operate at longer baseline than NS-HP-GN

3. NS-HP-GN2 has shorter RTK initialization time than NS-HP-GN

4. NS-HP-GN2 is capable of supporting PPP. Online PPP service such as OPUS、AUSPOS、CSR-PPP、APPS、GAPS...etc. require dual frequency data. Using a single NS-HP-GN2 and online PPP service, one can get centimeter-precise position anywhere on earth, while single-frequency NS-HP-GN cannot. 

We look forward to see your interesting applications with this more powerful RTK receiver.

With 2020 around the corner, we wish you and your family Merry Christmas and Happy New Year !

Cycle Slip Count in GNSS Viewer Update

Latest GNSS Viewer 20170712 version has Cycle Slip Count added. It relates to signal quality seen by the receiver, showing how many satellite signals has cycle slip detected when in Float RTK and Fix RTK state. Two cycle slip numbers are shown, left for the rover, right for the base. Below video shows low cycle slip [...]

New Milestone in Low Cost Single Frequency RTK Performance

Single frequency RTK receivers work well under open sky environment. But when tall buildings or trees are encountered, none has yet shown to work well, they lose RTK Fix and have position jumps. This $595 Multi-Band, Multi-Constellation RTK GNSS Receiver struggles too when near trees.Below video shows our soon to be released firmware update that could [...]

What's "-S" Version RTK For ?

-S version having RTK position stamp feature is mainly for UAV mapping application. It takes external positive edge camera trigger signal occurring on the TRIG pin and compute RTK position within closest internal 1msec tic and output in STI,005 message. For 50Km/hr flying UAV, max position error is 50e5/3600/1000 = 1.39cm on top of 1cm [...]

What's Moving Base RTK For?

GPS receiver output correct course over ground (COG) information when in motion. It represent movement direction. Without movement, the output COG information may be incorrect.Some applications, such as marine vessel autopilot, require knowledge of accurate heading direction regardless of movement direction.  Two NS-HP or NS-HP-GL configured in moving base RTK mode gives precise heading in the direction [...]

 NS-HP or NS-HP-GL are single frequency RTK receivers. For reliable consistent single-frequency RTK operation, they require 12 or more usable satellite signals above 15 degree elevation angle with SNR no less than 38dB/Hz. With 10 or 11 usable satellite signals, we've seen less than 0.1% rate of getting incorrect RTK Fix off by centimeters ~ decimeters. [...]
