GPS Restrictions Impact High-Altitude and High-Speed Craft

Understanding CoCom's Reach

New regulations are affecting the use of GPS receivers in high-altitude balloons and CubeSats. These rules restrict devices that function at extreme speeds or elevations. The changes are creating challenges for researchers and developers in aerospace.

The core issue stems from CoCom regulations, which govern the export of sensitive technologies. These rules aim to prevent the misuse of advanced navigation systems. They specifically target devices that could be used in missile guidance.

Why Are These Regulations Still Relevant?

The Coordinating Committee for Multilateral Export Controls (CoCom) was an organization during the Cold War. Its purpose was to control the export of technology to communist countries. Although CoCom dissolved in 1994, its principles still influence international trade laws. Many countries adopted similar export controls.

These controls often include restrictions on GPS receivers. A common threshold is 60,000 feet in altitude or 1,000 knots (about 1,150 mph) in speed. If a GPS device can operate beyond these limits, it falls under stricter export scrutiny. This makes it difficult for non-military projects to acquire such hardware.

# What are CoCom regulations?

The primary concern remains the proliferation of missile technology. A GPS receiver capable of high-altitude and high-speed operation could theoretically be integrated into a ballistic missile. Even if the immediate application is scientific, the potential for dual-use technology drives these restrictions. This creates a hurdle for projects like weather balloons and small satellites. These craft often exceed the regulated altitude and speed limits.

# How do these regulations affect scientific projects?

Researchers must navigate complex licensing procedures. They might also need to use specialized, less capable GPS units. This can compromise data quality or limit project scope. The regulations force innovators to find workarounds or accept limitations.

CoCom regulations refer to export controls initially established by the Coordinating Committee for Multilateral Export Controls. These rules restrict the sale of certain technologies, like advanced GPS receivers, to prevent their use in weapons.

# What are the typical GPS operational limits under these rules?

Scientific projects, such as high-altitude balloons or CubeSats, often need GPS receivers that operate beyond regulated altitude and speed limits. This can make it difficult to acquire suitable hardware or require special export licenses.

Many export controls on GPS receivers are triggered if the device can function above 60,000 feet in altitude or faster than 1,000 knots (approximately 1,150 mph). Devices exceeding these thresholds face stricter scrutiny.
