ECCN 6A007
NSMTATGravity meters (gravimeters) and gravity gradiometers, as follows .
What This ECCN Covers
ECCN 6A007 controls gravity meters (gravimeters) and gravity gradiometers meeting defined accuracy thresholds — for example ground-use gravimeters with static accuracy better than 10 µGal, and instruments designed for mobile or airborne use. Precise gravity sensing aids navigation and resource surveying but is also relevant to missile and submarine applications, hence National Security, Missile Technology, and Anti-Terrorism controls.
Who needs to check this?
Manufacturers of gravimeters and gravity gradiometers for geophysical survey, navigation, and research, and integrators of airborne or marine gravity systems.
Compliance tip
Control turns on static accuracy and operating environment (ground, marine, airborne) — confirm your instrument against the entry thresholds. The Missile Technology reason narrows license-exception eligibility; verify against the entry and apply Part 744 end-use diligence.
Items Covered
- a.Gravity meters designed or modified for ground use and having a static "accuracy" of less (better) than 10 µGal;
- b.Gravity meters designed for mobile platforms and having all of the following:
- 1. A static "accuracy" of less (better) than 0.7 mGal; and
- 2. An in-service (operational) "accuracy" of less (better) than 0.7 mGal having a 'time-to-steady-state registration' of less than 2 minutes under any combination of attendant corrective compensations and motional influences;
- c.Gravity gradiometers.
Control Reasons
Items controlled for national security reasons under multilateral export control regimes.
Items controlled under the Missile Technology Control Regime (MTCR).
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
