Leica uses the term Mechanical Reference Plane (MRP) instead of the more common (in the U.S., anyway) Antenna Reference Point (ARP). In the case of t...

I think I may have looked at removing them at one point, but if I *did* figure out how to do it I've long since forgotten what I learned. 🙁 Thinki...

I don't know about Leica, but Trimble has been inconsistent in this regard. I have a couple of R8 receivers: an R8 and an R8-3. I was given the R...

It's worth noting that if you operate as a sole proprietor or (probably) a general partnership, you're not required to submit a BOIR. There are a bu...

Fabric? Can you clarify? I used to use Microcentered and Compact L1/L2 antennas with the big ground planes for GPS (only) static work, but about 10...

A choke ring is better at rejecting multipath and may have a slightly better S/N ratio, but unless you're doing very long sessions (i.e. an infrastruc...

If vibrations are the concern, then it seems to me that the instrument question isn't optical versus digital, it's automatic leveling versus manual le...

It's been well over 20 years since I bought a Philly rod, but the last one I bought (Leitz) was disappointing. The graduations were kind of fuzzy, an...

I mean their subscription-only strategy probably makes sense for corporate operations with multiple seats, but for the solo operator like me who doesn...

The core functions of AutoCAD haven't changed much since my first introduction to R9. They've added many useful things -- and many more not-so-useful...

Amen. Union pensions can evaporate if industry conditions change dramatically, or if the pension is mismanaged (corruptly or otherwise). Local gover...

The drone thing is certainly interesting, but for my situation (solo operator approaching retirement with only a fraction of projects that would benef...

The reason I use the GMP101 all the time is because I usually set control as I go, even when most of my shots are for topo. I have a GRZ4 that I neve...

Do as you like, but I use a GMP101 for pretty much everything. I rarely carry topo shots more than 500' -- there's too much elevation error in long s...

I got the shake alert and thought, "This must be a mistake -- we never feel earthquakes here." Then the house started creaking. I moved to the doorw...

What if you need that corner for your survey and there isn't a monument there anymore? Is it okay to reset it at your calculated position, showing yo...

Here's a thought exercise: You tied a section corner monument into a tight control network (solid equipment and procedures, redundant ties, least squ...

I'm afraid I can't be of assistance -- I sold my PM2s years ago, and haven't had any Ashtech software for at least a decade. Any insight into Ashtech...
