Dual Frequency (or Multi-Band) RTK

Posted

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 !
