The product “here+ rtk gnss set” is showing centimeter level accuracy. Is this only applicable for open region? or it will show same accuracy under ostruction, say buildings, bridges as well?
Hello @deepak36ccny and welcome to the RobotShop community,
Accuracy will be affected by such obstructions.
You can find information about the accuracy of the Here+ on this page.
The base station needs a certain amount of time to meet the accuracy requirements of your input. Testing shows that, in an open area without shelter, to achieve the absolute accuracy of 2m takes a few minutes; to reach the absolute accuracy of less than 30cm takes around an hour; to reach the accuracy of 10cm takes a few hours.
