Spherefix SP Nano

The same RTK fix and the same tilted-pole shot as the SP30, in 176 grams. Corrections arrive over its own 4G modem, the controller talks to it over Bluetooth, and the whole rover is the head on the pole.

Where it fits

The second rover

Same fix as the SP30, a tenth of the weight, and two things it does not carry. Worth knowing which before you put it on a machine.

01

Same RTK fix

1408 channels · 5 Hz

GPS, GLONASS, BDS, Galileo, QZSS, SBAS and NavIC, on every band the receiver tracks — the same constellation list as the SP30, and the same ±8 mm + 1 ppm horizontal. Position updates at 5 Hz rather than 20, which is stakeout and topo rather than machine guidance.

02

Tilted pole

< 2 cm · pole to 60°

The same inertial correction. Hold the tip on the point, lean the pole clear of the wall or the back of the curb, take the shot. You stop levelling the bubble and the shot still lands.

03

176 grams

60 × 41.3 × 126.3 mm

With the helical antenna on. It goes on a pole your arm does not notice by mid-afternoon, and it travels in a jacket pocket — a second rover for a two-person crew without a second case in the truck.

04

4G in the receiver

LTE full band · Bluetooth BR, EDR and BLE

A SIM and an NTRIP mount point is the whole setup. There is no internal UHF radio, so it works from a network correction rather than your own base over radio. If you run your own base on UHF, the SP30 is the one you want.

The range

Nano or SP30

Both take the same RTK fix and the same tilted-pole shot. The difference is what else is in the housing, and what it weighs.

This page

SP Nano

176 g. Tilt survey, 4G corrections, 12 hours. No radio, no cameras.

Also available

Spherefix SP30

1000 g. Adds a laser, an AR stakeout camera, a 5 W LoRa radio, 20 Hz and 24 hours.
