Hardware Construction
The RTK Surveyor was made to work with low-cost, off the rack gear. Right here we’ll describe simple tips to build a Rover and Base.
Rover
Found right here is the most typical RTK Rover setup. A monopole made for cameras is utilized. A cell phone owner try clamped on the monopod together with RTK Surveyor is actually mounted. The ?” cam bond associated with the monopole is adjusted to ?” 11-TPI and a L1/L2 antenna is affixed. A Male TNC to Male SMA cable links the antenna towards the RTK Surveyor. No radio is necessary because RTCM correction data is provided by a cell phone over Bluetooth.
We now have complete plenty of assessment using the u-blox L1/L2 antenna and it’s excellent for any cost and proportions. Mounted to a ground plate you’ll get great results. It’s just some ungainly whenever attached to the top of a monopole. I encourage the ‘ufo’ preferences L1/L2 antennas simply because they need a larger antenna component and a slightly bigger crushed flat compared to the u-blox antenna.
If you are buying a monopole (aka monopod), get one that will be 65” in total or deeper to ensure that the antenna is going to be above your mind. We’ve have good-luck because of the Amazon Rules brand.
We strongly recommend against making use of a rigorous helical antenna setting as revealed below. The RTK Surveyor is not created for these types of designs and that can lead to long lasting damage to the antenna connector. The helical antenna turns out to be big lever arm. When the product are fallen this lever can perform harmful the SMA connector and where in fact the connector try soldered into the PCB.
If you are searching for a cell phone clamp make sure you buy one that will be appropriate for the diameter of your own monopole features a knob to improve clamp force. Continue reading “SparkFun RTK Surveyor Hookup Tips Guide. A monopole designed for digital cameras is employed”
