I’ve got a single RTK express, last summer I spent some time figuring out how to get it to its claimed accuracy and I’m really happy with that now! You can read that adventure in [this post (tl;dr you have to let it sit for 5 full minutes to stabilize)
BTW, the location where I’m doing this is up in the mountains and there is NO cell phone service from any carrier. Because of that, and my unwillingness to buy a second RTK, I’m stuck with DGPS.
Now I’ve got the opposite problem/challenge/opportunity. I’ve got some lat/long values that I want to find in the physical world. I can set the antenna in the approximate location for each lat/long position, wait 5 minutes, see if I got it right, adjust the antenna, wait another 5 minutes, lather, rinse, repeat, but I’d really rather not.
I’m using SW Maps to see what the RTK is thinking, is that still the best app out there that doesn’t cost $1000s? Is there a way to (1) load my lat/long points into the app, (2) pick a point, and (3) have it tell me (after the appropriate 5 minute settling-down period) where the point actually is compared to where the antenna is? If it tells me distance & direction I can grab a compass & reel tape measure and get close enough.
I’ll also reach out to SW Maps on this.
Then, when I move the RTK to the next location (my points are about 25’ to 50’ apart) I’m assuming I need to wait the full 5 minutes again?
Thanks!

Hello. I wish the same . If SWmaps had the point setting function it would be much more complete.
If you already have it, I haven’t found it.
Hopefully the creator will add it in future updates.
What you want to do, is t stake out points. You can do it. You need to add the points as Shapefiles. For this, you can use a Gis software. You have to add points manually into the gis software, later export them as Shapefiles and add this in the SW maps Folder, “Android\media\np.com.softwel.swmaps\Maps\shapefiles”, later in the program you add a new layer, you choose shapefile, and there you cann see your points. When u pick a point from the list, the swmaps will tell you yoour differentials in northing and easting. Hope this helps you.
Excellent.
It works with all the points you have saved, also with the points collected with gps.
You touch the screen and if there are many nearby points, a list opens for you to choose the one you want.
A screen opens with its description and below it shows you the differentials dx, dy and dz. It’s not the most comfortable but it works.
Positive dx differentials, you move to the right.
Positive dy differentials move “up” your maps.
I would like to know if you can see a list of the points collected, I have not been able to see it.
Greetings
I convinced Google Earth to output a KML file, and copied it into the Android\media\np.com.softwel.swmaps\Maps\shapefiles\kml folder, and was able to add them as a layer and they are showing up. So far so good!
But I can’t find any way to get it to show me the distance & direction from my current location to any of the points. If I click on one of the points, it just gives me a blank speech bubble, and I can’t find any way to use its ruler tool to measure from my location to one of the points (only from one of the points to another of the points). What am I missing? (screenshot attached)
Thanks!

You have to use a shapefile, not a KML file. SW Maps will not let you select points from a KML file.
