Setting up permanent base, data quality

Reach RS2 / RS2+ RTK / PPK configuration
1

Hello I am setting up a permanent base with an RS2. I have narrowed down my selections to a few sites. None of the sites are perfect. One of the sites has great sky visibility and a very secure anchoring position. I am somewhat concerned though about RF interference from electrical equipment in the vicinity. In the attached observations note that G03 has many cycle slips and switches a lot between L1 and L1/2. Also note that G14 experiences cycle slips at high elevation. Both of these things concern me about the accuracy of the corrections that will be sent by this base. Is this data quality acceptable?

Hi Derek,

Thanks for sharing the logs and details about your setup! I checked the L1 and L2 signal quality. Most satellites have an SNR above 45 for L1 and above 30 for L2, which is generally a good sign.


As you noted, it has some cycle slips and signal interruptions. That could be due to the electrical interference nearby. It’s hard to say for sure how much it will affect the stability of your corrections.

Since the site has great sky visibility and a secure mounting spot, it might still work well. The best way to know for sure is to test it. If you have another unit as a rover, I suggest running a short session to see how the corrections hold up in real use.
