ECCN 7A003
NSMTAT'Inertial measurement equipment or systems', having any of the following.
What This ECCN Covers
ECCN 7A003 controls inertial measurement equipment and systems (IMUs/INS) — including units that integrate satellite navigation or "Data-Based Referenced Navigation" — that meet specified accuracy thresholds for aircraft, land vehicles, vessels, or missiles. These systems provide self-contained position, velocity, and attitude data, which is why navigation-grade units are tightly controlled for National Security, Missile Technology, and Anti-Terrorism.
Who needs to check this?
Manufacturers of inertial navigation systems, GPS/INS units, and guidance packages for aerospace, marine, and autonomous platforms.
Compliance tip
As a Missile Technology entry, 7A003 generally does not permit license exceptions, and missile or UAV end use raises end-user controls under EAR Part 744. Classification hinges on stated position and velocity accuracy — review the entry's parameters and the associated Technical Notes for the conditions under which accuracy is measured.
Items Covered
- a."Satellite navigation system";
- b."Data-Based Referenced Navigation" ("DBRN").
- a.Designed for "aircraft", land vehicles or vessels, providing position without the use of 'positional aiding references', and having any of the following "accuracies" subsequent to normal alignment:
- 1. 0.8 nautical miles per hour (nm/hr) "Circular Error Probable" ("CEP") rate or less (better);
- 2. 0.5% distanced travelled "CEP" or less (better); or
- 3. Total drift of 1 nautical mile "CEP" or less (better) in a 24 hr period;
- b.Designed for "aircraft", land vehicles or vessels, with an embedded 'positional aiding reference' and providing position after loss of all 'positional aiding references' for a period of up to 4 minutes, having an "accuracy" of less (better) than 10 meters "CEP";
- c.Designed for "aircraft", land vehicles or vessels, providing heading or True North determination and having any of the following:
- 1. A maximum operating angular rate less (lower) than 500 deg/s and a heading "accuracy" without the use of 'positional aiding references' equal to or less (better) than 0.07 deg sec (Lat) (equivalent to 6 arc minutes rms at 45 degrees latitude); or
- 2. A maximum operating angular rate equal to or greater (higher) than 500 deg/s and a heading "accuracy" without the use of 'positional aiding references' equal to or less (better) than 0.2 deg sec (Lat) (equivalent to 17 arc minutes rms at 45 degrees latitude);
- d.Providing acceleration measurements or angular rate measurements, in more than one dimension, and having any of the following:
- 1. Performance specified by 7A001 or 7A002 along any axis, without the use of any aiding references; or
- 2. Being "space-qualified" and providing angular rate measurements having an "angle random walk" along any axis of less (better) than or equal to 0.1 degree per square root hour.
