U.S. Private Remote Sensing U.S. Private Remote Sensing SatellitesSatellites

U.S. policy supports a competitive U.S. commercial remote sensing industry for several reasons

U.S. companies are authorized to develop and launch commercial remote sensing satellites under:– Land Remote Sensing Policy Act of 1992– PDD 23: US Policy on Foreign Access to Remote Sensing

Space Capabilities (President Clinton, 1994)– U.S. Commercial Remote Sensing Policy (President Bush,

2003) Replaces PDD23 but similar

Military and civil agencies to rely on U.S. commercial systems for imaging needs

Shutter ControlShutter Control Shutter Control: 1992 Land Remote Sensing Act gives

the U.S. Department of Commerce the legal authority to limit the collection and distribution of commercial satellite imagery, i.e. “shutter control”, “when national security, international obligations, or foreign policy interests may be compromised”.

The government may place operational conditions or limitations on SAR or hyperspectral systems seeking licensure.

The US government also limits remote sensing of Israel.

US LicenseUS License The Licensee is obligated to “operate the system in a manner that

preserves the national security and observes the international obligations and foreign policies of the United States.”

Maintain and make available to the US government a record of all satellite tasking operations for the previous year

Data collection and/or distribution may be limited by the US government during periods when “national security or international obligations and/or foreign policies may be compromised.”. This restriction is commonly known as “shutter control”

The government of any country has the right to unenhanced data and images of territory under their jurisdiction.

US LicenseUS License The US government has the right to unenhanced data

for archival purposes. These data would be available to public after a reasonable period of time

Data to be purged by a licensee must be offered to the US government for archival purposes and would be immediately available to the public

The US government must be notified of any substantial agreements that the licensee intends to enter with any foreign nation, entity or consortium. The foreign party must comply with license regulations

The Future of the FutureThe Future of the Future MEMS-Microelectromechanical systems and

nano technology will begin to impact remote sensing

“Smart Dust” – Sensors so small they float in the air (Kris Pister-U.Cal Berkeley) self-powered smart sensors with a 5 sq mm computer (asprin tablet), costing 10 cents now (down to dust size for a penny)

Intelligent multitasking, sensors that communicate and make “group decisions” with on-board processing and linked with in-situ systems to trigger when, where and what to acquire, process, and distribute

In ConclusionIn ConclusionUltra high resolution systems are

opening new areas of space remote sensing applications

“Dual Use” issues are importantNew technologies like hyperspectral

systems will become the norm and improve data extraction and analysis

Micro technologies are on the horizon

Major questionsMajor questions How many of these do we need? What are the

drivers? Archiving/storage/protection/retrieval of data Open skies vs. national interests and national

security “Global good” vs. national interests/private profit Is more really better? Global .1 meter/256

channels/12 bit daily data? How can we handle this? Who will use it?

It’s just a tool, the use of the tool is in human hands, we will decide how they are used.
