Scintrex - Model FG5-X - Marine Gravity Meter System- Brochure

MGS - 6 MAR INE GRAV I T Y S Y S TEMThe latest in a line of Marine Gravity Meters going back over 50 years. The MGS-6: Smaller, lighter, and over 100X more quiet than its predecessor.M ICRO-G LACOSTE IS PROUD TO ANNOUNCE the next generation of marine based dynamic gravity meters: The Marine Gravity System-6 (MGS-6). It represents the next generation in a long line of L&R-based dynamic gravity systems, stretching back to the first successful dynamic gravity meter tests on ships more than 50 years ago. Note though, that the MGS-6 is more than a simple upgrade to the Air-Sea System II (AS-2). The MGS-6 is based on the smaller, lighter, more power-efficient TAGS-6 (airborne) platform, and employs the same full-force feedback sensor. In both systems, the platform control and data acquisition system have been overhauled, resulting in unparalleled data quality.• Smaller sensor/gimbal (60%).• Lighter sensor/gimbal (30%).• New slip ring technology on the gimbal makes for a more robust and reliable stable platform.• Larger pitch (25° vs. 22°) and larger Roll (35° vs. 25°) ranges.• Full feedback: ± 500,000 milliGal range on beam.• 100 times the dynamic acceleration range.• Double oven temperature control.• Temperature controlled electronics.• Separate, rack-mountable electronic unit and computer allow for more flexibility in configuration.• Lockable gimbal.• System ships with gimbal installed in frame.• Static repeatability improved (0.02 vs. 0.05 milliGal).• Reduced power requirements (75 vs. 240W).• Greatly reduced frame size: 48% smaller (59 x 53 x 56cm vs. 71 x 56 x 84cm).• Greatly reduced weight (101kg vs. 121kg, including UPS and electronics).NEW FEATURES• Full feedback: ± 500,000 milliGal range on beam.• 100 times the dynamic acceleration range.• Double oven temperature control.• Temperature controlled electronics, accelerometers, and Fiber Optic Gyros.WWW.MICROGLACOSTE.COM NEW FULL FORCE FEEDBACK SENSOR:APPLICATIONS INCLUDE• Geoid Mapping • Regional Geophysics • Petroleum Exploration • Mineral Exploration150100500-50-100-15001/2701/2601/25/14 01/28S-180 weekend data in gimbals = 23.4 µGalsDate/timeETGTAB tidesS-180µGalsSAMPLE DATA:New system is 100x quieter than older air-damped and magnetic-damped systems.
