SIG-801 is an all-in-one 3-axis fluxgate magnetometer with high accuracy. Piccolo(TM) compatible command set is a subset of the SIG-801 commands. Piccolo is a trademark of Collins Aerospace.

The technology employed in the Applied Physics Systems magnetometer product line is generally referred to as a fluxgate technology.

The Applied Physics Systems SIG-803 fluxgate magnetometer measures magnetic fields on 3-axis and converts and transmits over its serial port (at 38400 baud)

The Applied Physics Systems SIG-804 is a small, low cost magnetometer designed to measure small magnetic fields (.02 milligauss to 5 Gauss).

The Sigdrill SIG-805 telemetry MWD system communicates by transmitting electromagnetic waves through the formation instead of pressure pulses through a fluid column.

The Applied Physics Systems SIG-806 heading sensor is a high performance, fully calibrated, narrow diameter heading sensor ideally suited for defense sonar array and marine seismic streamer applications.

The Applied Physics Systems SIG-807 accelerometer provides highly accurate and stable measurement of acceleration, vibration, and gravity over a wide range of temperatures and over years of time

The Applied Physics Systems SIG-808 Directional Sensor is our flagship survey instrument that enables high accuracy measurement of the toolface (roll), inclination, and azimuth orientation angles in borehole
