GPS and LiDAR beginner

Hey there,

I have just joined so forgive me if I am posting in the wrong place.

I am a site engineer here in the UK and I have created my own company for setting out works etc. I have predominately been using a Leica TS16 to stake points and lines etc but I want to branch out into GPS and potentially LiDAR drone surveying so I can start to add this to my service list.

From what I have gathered so far, PPK seems to be the best option for LiDAR. Can I use any base station (e.g. Leica iCON GPS 70) or is there a certain type I need to look out for? I see the Emlid being mentioned a lot.

Where is the best place to start to get my head around all of this? (apart from trawling through here and watching YouTube vids) are there any other resources?

We like the Emlid Reach RS2 due to the affordable price and simplicity of operation.

It’s just too easy. Of course others work fine, their workflow just might be a little more in depth than the RS2.

Do you just use the Reach for drone works?

We do a lot of site work (staking out roads/drainage etc) which we need a GPS for as well as topographical surveying.

I am looking for a GPS to serve all purposes, but it is hard to look past the Emlid due to the price.

I use the RS2 for shooting targets and locating features that aren’t obtained from the ortho aerial. It does do stake out, but I haven’t used it for that.

You run the reach for 2.5 hours? I had no idea. I’ve just been running it for maybe 15 min above my flight time, which is less than that.

You can probably get away with doing 2 hrs + but we like to stick to the standard 2.5 or more to provide the most precision. Of course this is all dependent upon your accuracy needs, so if you are just doing a test and don’t need the data accuracy but just to see the points then it’s not as much of an issue as long as the Base Station is running during your flight.

That seems like something that should probably be in every single tutorial and instruction. Even in the youtube video it doesn’t say that. Even the subcontractors I’ve hired didn’t wait that long. I have always had it running before/during/after by a little but didn’t know that extent.

To qualify that even further Daniel, if you want an OPUS solution you need to log for a minimum of 2 hours. If you aren’t concerned with OPUS then your current workflow is totally appropriate.

Ok good- that’s a relief. Thanks for the clarification!
