I am using a laptop for the committee boat that doesn't have a GPS chip. Is there anything that I can do to see my position in the Commander app

The Commander app uses native OS sensor data for displaying your position.

If your laptop doesn't have a sensor but your committee boat has instruments, you can use tools like GPS Sensor Drivers (https://www.gpssensordrivers.com/) to create a virtual sensor that pulls location data from your instruments.
