HJ-Arrow GNSS equipment offers the following interfaces with the National Land Surveying and Mapping Center's e-GNSS service:

1. A private base station provides UAV corrections over RF
2. The UAV connects directly to the national surveying center for corrections
3. A private base station provides corrections over a mobile network
4. A private base station uses VBS-RTK to further correct its own position

RTK-Lite receives multiple satellite constellations, including GPS, GLONASS, Galileo and BeiDou.

It can use a mobile phone or built-in SIM card to connect wirelessly to the national surveying center's e-GNSS server for high-precision real-time kinematic positioning.
The source presents HJ-Arrow GNSS as a high-performance product for varied surveying needs and applications, and invites questions, suggestions and product enquiries.

FROM THE RECORD TO YOUR REQUIREMENT

Define one useful
first output.

The HJ-Arrow and RTK records explain available hardware. Product positioning figures do not automatically establish landing accuracy for your aircraft.

What you provide: Required accuracy, sky visibility, correction service and controller.
What to define together: A positioning configuration and verification checklist.

Exact hardware and software versions, interfaces, operating conditions, budget, schedule and responsible people remain to be agreed.
