I have a question. I have a twin-engine boat and I want to implement an autopilot in it. Using GPS alone my boat goes to the destination like a sine wave, unfortunately for 300m. Just like the picture below. enter image description here

I Use RadioLink M8N GPS SE100 (http://radiolink.com.cn/doce/UploadFile/ProductFile/SE100Manual.pdf) and STM32. It has a built-in geomagnetic sensor HMC5983. Is it possible to use this sensor and GPS to let my boat go straight?

I don't know much about all those Kalman filters, Fusion, etc. My question is what should I use, apart from the GPS itself, what kind of sensors and filters to make my boat sail in a straight line.

Thanks in advance for the tips and hints.

It is important to position a boat. If you only use poor GPS receiver, you couldn't do this. In order to solve this, you should apply UKF(unscented kalman filter) with fusion of GPS and INS.

According to ublox documentation it is possible to enable fusion filter for M8N and feed the data to it.
