A prism constant is a given property of the particular prism model that defines the relation of the distance measurement to the mechanical reference point of the prism (the holder). When the EDM emits infrared beam to the prism, it hits the corner cubes of the prism then the beam is returned along the same path parallel to the incoming beam. Now there is an error called angular beam deviation in this returned path to the EDM. This error (angular beam deviation) is caused by the path travelled by infrared beam in the prism i.e. look diagram A the path a, b and c

The FOIF EL302A host complete range of applications from first order levelling tasks to the construction site. The wide screen display and alphanumerical keyboard with integrated measurement programs track the work done and make productivity much quicker. The keyboard specifically provides comfort and high efficiency when working. Each of the digital levels save the distance to the staff and with one simple press of a button calculates the height of the point. An easy to use measuring program allows for quick and reliable height difference measurements, stake outs and line levelling. The ‘point to point’ function continuously reads and gives height differences which are shown on the display allowing the data to be checked and monitored. Measurements are also free of earth curvature influence when the correction feature is enabled.

How Many Waypoints are There?

Waypoints are reference points and they help to show your location. They are extremely useful in helping to sort the best routes for your trip as they leave a kind of breadcrumb trail for you. It is suggested that a decent handheld GPS should be capable of storing at least 500 waypoints. That way you are covered whether you are on the water, in the wilderness or on the road.

Do I buy wooden tripod, aluminum tripod or fiber glass tripod?

When purchasing a Construction or Surveying Grade Tripod there are several different options to choose from, the material, the head, the clamps, and these are just standard options. The type of surveying tripod you need to buy will depend on the instrument it will support and the work conditions or environment. With this blog, we have put together helpful information to assist in deciding what the best options are to meet your needs.

A Laser Distance Meter* sends out a finely focused pulse of light to the target and detects the reflection. The meter measures the time between those two events, and converts this to a distance.

The formula is simple: Distance = Ä (Speed x Time). However the speed of light is 300,000 km per second, so to resolve differences of (say) 1 cm, the meter must measure time intervals of the order of billionths of a second. But don’t worry – the technology is well established and reliable. A laser distance meter can measure distances of up to 30m with an accuracy of ±3mm.

Unmanned aerial vehicles (UAVS), also known as drones, are aircraft either controlled by ‘pilots’ from the ground or increasingly, autonomously following a pre-programmed mission. 

        There are two basic types of drones—fixed-wing units with a brush less electric motor and a rotor type that has between three and eight or more brush less electric motors (commonly referred to as multirotors). The rotor units enable drones to hover at a precise altitude and position and operate in confined airspace. The technology for both systems relies on the featherweight lithium polymer battery that stores an incredible amount of power and the brush less motors that have a large variable speed range with good power at all speeds, lightweight air frames and a simple, hobby-type airplane radio controller.
