SOURCES SOUGHT: This is a SOURCES SOUGHT NOTICE. The U.S. Geological Survey is conducting a MARKET SURVEY to determine the interest and capability of any firm eligible to compete under NAICS code 334519 with a Small Business Size Standard THIS IS NOT A SOLICITATION. ALL COST ASSOCIATED WITH PROVIDING INFORMATION AS REQUESTED BY THIS SOURCES SOUGHT NOTICE SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR. Submission is voluntary. General DescriptionA fully automated/robotic declination/inclination fluxgate magnetometer (DIFM) theodolite, providing automatic absolute measurements of geomagnetic declination & inclination. As a fully automated/robotic instrument, the DIFM theodolite must continuously work without any human support. The measurement sequence must follow the same protocol as a conventional ¿manual¿ DIFM theodolite measurement sequence:¿ Horizontal direction Referencing: 2 target pointing (sensor up and sensor down)¿ 4 declination measurements: east-up, west-down, east-down and west-up.¿ Horizontal direction Referencing: 2 target measurement (to check the mechanical stability)¿ 4 inclination measurements: south-up, north-down, south-down and north-upCombined with a scalar instrument (e.g., proton precession magnetometer), the DIFM theodolite must absolutely measure the geomagnetic field vector in orientation and in strength and determine variometer baselines (e.g., X0, Y0 & Z0).The mechanical part of the instrument must consist of a non-magnetic platform having two major degrees-of-freedom in rotation (a vertical and a horizontal axis). The motion is ensured by non-magnetic ultrasonic motors. Each axis is equipped with non-magnetic angular encoders providing angle readings with 1arcsec (1/3600°) resolution. A single axis magnetic sensor (fluxgate sensor) is mounted on the horizontal axis in order to determine the different positions perpendicular to the magnetic field. Levelling the instrument can be performed by turning the three foot-screws an...
