What will the quotation include?
Confirm the selected SKU, antenna, strap or bracket, power supply, software licensing and service terms in the quotation.
How should I verify positioning accuracy?
Positioning accuracy depends on reference coordinates, baseline, sky visibility, antenna setup and correction age. Validate results against independent check points and your project requirements.
What is required for dual-antenna heading?
Confirm the two external antennas, mounting orientation, baseline, cable routing, receiver configuration and host interface. The 0.1° RMS heading specification is tied to a 1m baseline.

APPLICATION & SELECTION
Vehicle GNSS positioning and heading as one integration
Specify the external antenna pair, antenna baseline, terminal bracket, DC supply protection and machine interface together. GK101M is designed for a powered installation and has no built-in battery. Positioning data integration does not by itself provide an automatic steering controller.
What is needed for GK101M dual-antenna heading?
Two suitable external antennas, a defined mounting baseline and orientation, matched cabling and receiver configuration are needed. The stated 0.1° RMS heading specification is tied to a 1m baseline; validate the complete installation.
Can GK101M be integrated into an agricultural vehicle?
Evaluate the mounting position, 9–24V DC supply, power protection, serial or Ethernet protocol and correction source. Steering, machine control and safety functions depend on the vehicle application and engineering integration.
