That is simply not feasible. RFID is extremely short ranged, certainly nothing of the range that could reach satellites.
It might work from 50 meters, but if they were within 50 meters anyways . . .

Hybrid Tag Includes Active RFID, GPS, Satellite and Sensors
Feb. 24, 2009—Numerex, an Atlanta-based provider of fixed and mobile machine-to-machine wireless solutions and network services, and RFID systems supplier Savi Technology have unveiled an intelligent hybrid tag that combines active RFID, satellite communications and Global Positioning System (GPS) technologies. The tag is designed to track goods anywhere within a global supply chain, whether they are waiting in a warehouse, being loaded onto a ship or sitting in a desert at a bare-bones military outpost.
The tag, known as the ST-694 GlobalTag, has been in development since the summer of 2007, as part of a cooperative research and development contract for the U.S Transportation Command (USTRANSCOM), the U.S. Department of Defense (DOD) group responsible for creating and implementing global deployment and distribution solutions for the U.S. military and government.
Therefore, Savi Technology and Numerex opted to marry satellite and GPS tracking with active RFID into a single device controlled by one microprocessor. Not only can the tag automatically and intelligently switch between active RFID and satellite communications as necessary, but the data can be viewed using a single back-end system.
The ST-694 includes an active Savi tag that complies with ISO 18000-7, the standard for real-time locating systems that employ active tags operating at 433 MHz. The ST-694 also includes the SX1, a tag unveiled one year ago by Orbit One, a division of Numerex. The SX1, which comes with a field-replaceable lithium battery, an internal motion sensor and an integrated GPS chipset, communicates with Globalstar's low Earth orbit (LEO) satellites (see Orbit One Launches Satellite-Based RFID Service).
Additionally, the ST-694 comes equipped with a motion sensor. In the event that motion is detected for at least a half-hour, the sensor will automatically instruct the tag to operate in satellite communications mode.
There have also been prototype hybrid tags that combine RFID and satellite communications. In 2005, in fact, the Department of Defense tested a version that included a Savi active tag (see DOD Tries Tags That Phone Home).
A year ago, Siemens IT Solutions and Services conducted a proof-of-technology test on a solution that combined active RFID transponders and sensors with GSM and GPRS telecommunications technology installed on ships. The solution communicated the RFID and sensor data to a satellite telecommunications service operated by Inmarsat (see Cargo-Tracking System Combines RFID, Sensors, GSM and Satellite).
The above notwithstanding: I think we can all agree that the epitome of technology is never found in commercially-available products. For that, you'd have to find the 'black products' that are held in secret, as war reserve or for the sake of espionage. Some of us will expect such 'black products' to be embedded in US-made war materiale, despite any assurances to the contrary.

CONFIDENTIAL TO GeorgeWelch: I will admit that there is a trust deficit among many Indians concerning the intentions of Americans, if you will admit that this mistrust is a two-way street, and Americans are also mistrustful of Indian's intentions.
In this context, the American mistrust of India is a motive
I strongly disagree with this.
If there is any mistrust on the US side, it is related to the nuclear weapons and tests thereof.
There is no mistrust about the use of fighters, bugging the fighters would provide no info on nuclear activities and so there is no motive.
If you must, you may "strongly disagree with this" in one breath, and in the very next, qualify that statement with a very big "If
there is any mistrust on the US side, it is related to the nuclear weapons and tests thereof." However, you should recognize that America's collusion
with the TSP's own nuclear weapons program, plus gifts of F-16s and Harpoons, et cetera; only serve to give Indians a solid basis for their mistrust of America.
Please stop pretending that any mistrust of American policy or strategy is some kind of knee-jerk anti-Americanism. It is not.
Rather, it is a learned response that was trained into us by honest observation, bitter experience and bloody truth.
If this serves to hurt American business interests, well, that's just karma.
