RTK is well known for land survey and automated precision farming applications, which are low speed or static. With emergence of lower-cost single frequency RTK receivers for less demanding applications (cm-level accuracy yet with shorter baseline not beyond 10Km and longer time of around 2 minutes to reach initial cm-level accuracy solution) we are interested find out how it performs under dynamic situation.
A road test was performed on a car; we see that it could maintain RTK fixed solution (meaning cm-level accuracy) up to 81Km/hr; it’s over speed limit of the road on which we are testing, not the limit of the receiver though.
Currently we are still using survey grade antenna to first understand performance capability of the single frequency RTK receiver, not to be limited by performance of smaller antenna in these early tests. After more testing done understanding the performance capability, we'll try smaller antenna on quadcopter!
