From the dealer side of things any “next generation” equipment from any manufacture is always a step forward. Sometimes those steps aren’t that big, however in the past year or two GNSS equipment have taken a large step. On the Leica side, a brand new GS14 to GS18t is massive improvement in performance tracking in poor conditions.
It is important to understand that most manufacturers might use similar parts for their GNSS boards however each manufacture uses their own measuring engine and this is were the real difference between manufactures and generations of equipment show their worth. So just because two pieces of equipment can track the same GNSS signals, this doesn’t mean they process it’s position the same way even within the same manufacture. For example a budget antenna might not have the same I.P. as that same manufactures high end equipment.
As for the tilt in the GS18’s accuracy and reliability claim. The reason they can achieve this is because the unit has a VERY nice IMU and not a tilt sensor. Thus no need for calibration because its not using a magnetic compass or tilt sensor.
i never had any complaints about what i could get done with a gs14. in fact, had several opportunities to shoot things in parallel with other surveyors who had various other (mostly different shades of yellow) equipment and would fix just as rapidly and reliably almost every time- maybe every time, nothing really jogs the memory otherwise.
have had a gs16 now for a couple months- which i understand to be an 18 without the tilt (don’t get me wrong, i just didn’t want to pay the premium)- and it fixes under all kinds of stuff i wouldn’t expect. repeatedly. and yes- reliably. i don’t push it too often in iffy conditions, but when i do i have always made sure to either go back much later and re-tie it, or else check it off traverse with the robot. i’m still not yet taking it for granted, as it usually strikes me as a little too improbable. but the residuals on redundant ties have been, generally, tight as can be.
