Spherefix SP30
Three ways to take a point: RTK on the pole, a tilted pole where you cannot plumb it, and a laser on what you cannot stand on. Set up and supported by the crew that carries one on its own jobs.

How it takes a point
Four ways to get the shot
One receiver on the pole. The two cameras and the laser are for the shots that used to mean a second trip or an offset.
RTK fix
1408 channels · 20 Hz
GPS, GLONASS, BDS, Galileo, QZSS, SBAS and NavIC, on every band the receiver tracks. Corrections over 4G from an NTRIP service, or over the built-in 5 W LoRa radio from your own base.
Tilted pole
< 2 cm · pole to 60°
The inertial module corrects for the angle of the pole, so you stop chasing the bubble on every shot. Corners, the base of a wall, the back of a curb: hold the tip on the point, lean the pole out of the way, take the shot.
Laser
≤ 2.5 cm · within 5 m
A camera aims a laser at the point you cannot stand on: a footing under water, the lip of a live manhole, the far side of a trench. The receiver reads the range and works out the coordinate from where the pole is.
AR stakeout
1080p · 70° view
The wide camera puts the design point onto a live picture of the ground in the controller. You walk to the mark on the screen instead of reading north and east offsets.
Photographs
On our own jobs
Not a studio. The SP30 on a pole and on a tripod in Ontario, and the kit as it arrives.
