The Design

MSRIV Esprit is the fourth generation MSR. This is the fastest scanning radar in the industry, MSRIV Esprit was designed to operate in highly volatile atmospheric conditions. It can detect a failure up to a rate of 13 500mm/h, the highest in the market.


Scan Speed

3D measurements are taken in less than two seconds repetitively, nearly eliminating all the false movement measurements from atmospherics. The atmospheric changes in two seconds is minimal.

A high scan speed produces the truest data, there is almost no compensation for required for false movement due to atmospherics. Therefore, an insignificant amount of data is lost in processing to eliminate noise.

Instantaneous 3D area measurement

A whole area is scanned instantaneously. This ensures that environmental changes will not produce unreliable measurements.

Critical and strategic monitoring

Critical monitoring: the high scan speed and instantaneous 3D area measurements detect rapid failures up to a rate of 13 500 mm/h effortlessly.

Strategic monitoring: due to the miniscule noise and interference, small movements is now easily detected. This results in predicting potential failures earlier and increasing warning times.


The distance of the system from the pit slope, and therefore the point spacing generated for the synthetic map is paramount for defining the longitude and precision of resolution for which alarm settings are based. The finer the precision and therefore the resolution, the more refined the displacement trend data will be for smaller detectable areas.

MSRIV Esprit offers an operating range up to 4 000 m, providing resolution options that are exceptional. The better the radar’s resolution, the better the probability to detect sub-bench failures at longer distances.
Operating Range
Range resolution
Maximum azimuth resolution
Maximum elevation resolution
500m 0.5 1.38 0.74
1000m 0.5 2.76 1.47
2000m 0.5 5.52 2.95
4000m 0.5 11.03 5.90

Moving Targets

The ability to do instantaneous area measurements excels to track and detect moving targets such as trucks. This produces greater coverage in areas where there is moving machinery and increases safety.
