Throw them out, they collect L1 data, do your flight, send it in for processing, voila.
From the ad;
ThereÛªs no more need for awkward and expensive survey gear. We can show up on site, quickly disperse the AeroPoints and then fly.Û
Saw them at a Trimble Demo today.
If you're more than a few miles from a CORS, you're not going to be able to tie to SPC. There datum is assumed and can not use the data to compare with future or past flight's.

Well I guess they are only $600 a piece + shipping, as they say, only $6000 for 10 targets. You still have to throw them out on the site.
So you have to set up a base... we're doing that anyhow. The question I have is do I have to send it to them to process or can I download it and process it myself?
No base needed, just a Dual Freq. static should be added to the set.
These are L1 static receivers, with wifi to upload data to a cloud. The manufacture provides post processing services via cloud service.
Corrections Network Access
Every AeroPoints purchase includes 1 year of corrections network subscription plus 3 additional data sets.
The trouble is non-surveyors see this as a cheap way to establish control. Maybe it is.
Will AeroPoints work in my area?
PropellerÛªs AeroPoints work everywhere in the world where thereÛªs solid ground and sky. However, for the accuracy required by most surveying purposes, which accounts for things like continental drift, they do need to be linked back to a known base point. This can happen in a few ways:
1. Fully automated processing in base station network coverage areas: Propeller has an extensive corrections network in many countries ÛÒ and this is expanding all the time as more drone teams start using AeroPoints. This is definitely the best way to use the AeroPoints. Let us know if youÛªre not on the map today ÛÒ weÛªre expanding our coverage network every week.
Global accuracy: the best available, 2cm/2cm/5cm
Consistency: the best available, 2cm/2cm/5cm
Internal accuracy: 1cm or less ÛÒ precise internal reconstruction
2. Provide your own corrections: You might have access to a dual frequency L1/L2 RTK rover, or the site may have an RTK base station receiver. You can provide us with RINEX formatted GNSS observations for the period of your survey and we can use that as the reference point.
Global accuracy: the best available, 2cm/2cm/5cm
Consistency: the best available, 2cm/2cm/5cm
Internal accuracy: 1cm or less ÛÒ precise internal reconstruction
3. Use an AeroPoint as a base station on a known mark. You can place one of the AeroPoints at a known survey mark or benchmark location. It needs to be activated for the duration of the survey. We can then use this AeroPoint, combined with the known coordinates of that mark, as the reference point for the other AeroPoints used in the survey.
Global accuracy: If you place the AeroPoint accurately, the best available, 2cm/2cm/5cm (plus the accuracy of the mark itself)
Consistency: If you use the same known mark each time, the best available, 2cm/2cm/5cm
Internal accuracy: 1cm or less ÛÒ precise internal reconstruction
4. Use an AeroPoint as a makeshift base station. If there are no known marks, the accuracy of your data globally will be reduced. However, you can still use AeroPoints to get results that line up with each other over time. Find somewhere recognizable that wonÛªt move and establish your own Û÷markÛª. The first time weÛªll calculate an estimated point, accurate within 50cm, and after that treat that co-ordinate as a Û÷known markÛª. YouÛªll need to place the AeroPoint on this exact mark each time.
