技术问答

Previously, SKYLAB(天工测控) has developed and launched SKG12UR, SKG12XR, SKG123L, SKG123S and SKM2105NR.

Now SKYLAB has teamed up with Huada Beidou to develop and launch higher-performance RTK Positioning Modules SKG122ER and SKG122GR. They are single-frequency multi-mode RTK modules and dual-frequency multi-mode RTK positioning modules.

This module can be used in vehicle navigation, unmanned driving, agricultural drones, lawnmowers and tower cranes.

At present, these two modules have been tested, and engineers who need outdoor high-precision positioning modules can call for samples.

RTK Positioning Module SKG122ER, SKG122GR Introduction

The RTK positioning modules SKG122ER and SKG122GR are satellite receiving modules that can support GPS, Beidou, GALILEO, QZSS and SBAS at the same time. They also support the reception of Beidou-3 signals.

The RTK algorithm is integrated in the positioning module. Combined with RTK services, centimeter-level positioning can be achieved. The module can be turned into a mobile station by configuration. These two modules can meet the dual needs of Beidou-3 positioning and RTK positioning. In application, it can meet the strict requirements of professional positioning and personal consumption needs.

The two modules of the industrial standard have a cold start time of <28s. It has excellent satellite search and positioning performance, supports PPS timing and has an accuracy of ±20ns. PPS is associated with NMEA, and the module has the function of antenna detection.

The module is an SMD stamp hole package in a classic 16*12 package. Compact size, compatible with international mainstream navigation and positioning modules on the market. Using SMD pads, supports standard pick and place and reflow soldering.

RTK Positioning Module SKG122ER, SKG122GR Positioning Accuracy

(1)SKGKG122ER

◆The tracking sensitivity of SKGKG122ER is -162dBm

◆Data update rate up to 20Hz

◆Location accuracy in open sky is 2.5m

◆The positioning accuracy in D-GNSS mode is less than 1m

◆The positioning accuracy in RTK mode is 2.5cm+1ppm(H)

(2)SKG122GR

◆The tracking sensitivity of SKG122GR is -167dBm

◆The number of tracking satellites reaches 40

◆The maximum data update rate in PVT mode is 10Hz

◆The maximum data update rate in RTK mode is 5Hz

◆Location accuracy in open sky is 2.5m

◆The positioning accuracy in SBAS mode is 2m

◆The positioning accuracy in D-GNSS mode is less than 1m

◆The positioning accuracy in RTK mode is 1.5cm+1ppm(H), 6.5cm+1ppm(V).

The above is a comparison of the single-frequency multi-mode RTK high-precision positioning module SKG122ER and the L1+L5 dual-frequency multi-mode RTK high-precision positioning module SKG122GR.
