Usually, the GPS antenna plays a crucial role in the functionality of a GPS tracker. It receives signals from GPS satellites, enabling accurate location determination, real-time updates, and overall improved performance of the device.

We have undergone a series of antenna advancements in our journey towards improvement. Starting with an onboard PCB antenna in v1.0, we progressed to ceramic antennas in v1.1 and v1.2, experimenting with different layouts along the way. Currently, we are in the testing phase of a shrapnel antenna for v1.3, which has already demonstrated remarkable outcomes, accurately pinpointing over 99% of GPS locations on the map.

You might also want to learn how we test the GPS antenna accuracy. Here are the steps that we took to review the accuracy of the V1.0 antenna and V1.3 antenna. One of our testing engineers took his daily car routine to work as the reference routine, then our engineer took the tracker with V1.0 antenna and V1.3 antenna to record all the reported locations on the routine. When we got the 2 GPS location pins on the map, we compared them with the reference routine, and calculated deviation. One more thing, apart from this routine, we also repeated the test in different locations and considered factors like environmental conditions to make sure we got the accuracy right.
