Hey everybody, this is my first post here. I'm curious if any of y'all have recently purchased the L5 Tracking OAF, and if so, did you notice any difference? I realize that we don't have a full constellation yet, just curious what sort of results you're now seeing, especially in challenging environments. The overwhelming majority of surveying I do is in Appalachian jungle, but I've seen pretty good results from my Topcon GR-5 with just GPS/GLONAS under the winter canopy. I feel like it'll eventually be worth the $900 upgrade, but I'm not sure whether it'll make the difference in getting a fixed position in places where I'm currently only getting an autonomous solution.

I'm working daily with full GNSS receivers (base+rover equipments) and I realize, the biggest improvements are consequent to the build up of the Beidou and Galileo orbital segment.
In many sites, with a lot of obstructions, more satellites can reduce dramatically DOP values ....
Advantages of L5 should be:
Cause the satellites with L5 are few, is difficult to compare the performance with 3rd frequency and its improvements with the contribution of Beidou and Galileo.
Have a nice day!
Im really looking to get into Robotics, are there any instruments or data collectors you can recommend to me?
I have been using robotics for 20 years or so. I have used Topcon, Leica, GeoMax, Geodimeter, Spectra Physics and Trimble. I did not have good experiences with early models of the Trimble or Spectra Physics so I have stayed away from them. The Topcons were adequate but somewhat slow and finicky locking on target. The Leica is exceptionally fast does not require any type of "active target" or any attachments to the rod to help find the prism and I have had excellent support from Leica staff. GeoMax is also an excellent robot and is comparable to Leica at a lower price point. As far as software goes I have used Carlson, Survey Pro, Magnet and Field Genius. My pick is Field Genius it works with most equipment except for the newer Trimbles and they have great tech support. Field Genius is very powerful for both land surveying and stakeout. As far as controllers go my favorite is a Mobile Demand windows tablet with 4 gb ram that has been used daily for over three years and no problems. Pricey but well worth the price if speed and large bright screen are needed. On the less expensive side I use GETAC PS 336 they are sturdy reliable. I also use a Ranger 3 which is comparable to the Getac in performance but has a better keyboard but cost more.
