Control Policies

ABSTRACTThis article analyzes differences between United States and West German export controls. It shows that United States controls are more extensive and stricter than controls in West Germany. Three possible explanations for this variation in policy are considered. First, these two states differ in regard to their positions in the international system and in their choice of economic strategies. Second, the extent of domestic political support for strict export control policies varies between the two countries. Finally, West Germany lacks the institutional framework to adequately control its foreign trade. The evidence presented corroborates the first two alternatives, while institutional explanations receive relatively little support. The article then discusses the historical development of United States and West German export control policies and institutions. The analysis shows evidence of both change and stability. More specifically, the article questions the argument that institutions in foreign economic policy, once established, persist and resist change, instead of adapting to environmental changes. Several hypotheses are considered to explain why in the area of export controls changes in policy, and to some extent institutions, occurred more frequently in West Germany than in the United States.

Global Navigation Satellite

The global positioning system (GPS) receiver has been one of the most important navigation systems for more than two decades. Although the GPS system was originally designed for near-Earth navigation, currently it is widely used in highly dynamic environments (such as low Earth orbit (LEO)). A space-capable GPS receiver (GPSR) is capable of providing timing and navigation information for spacecraft to determine the orbit and synchronize the onboard timing; therefore, it is one of the essential components of modern spacecraft. However, a space-grade GPSR is technology-sensitive and under export control. In order to overcome export control, the National Space Organization (NSPO) in Taiwan completed the development of a self-reliant space-grade GPSR in 2014. The NSPO GPSR, built in-house, has passed its qualification tests and is ready to fly onboard the Triton satellite. In addition to providing navigation, the GPS/global navigation satellite system (GNSS) is facilitated to many remote sensing missions, such as GNSS radio occultation (GNSS-RO) and GNSS reflectometry (GNSS-R). Based on the design of the NSPO GPSR, the NSPO is actively engaged in the development of the Triton program (a GNSS reflectometry mission). In a GNSS-R mission, the reflected signals are processed to form delay Doppler maps (DDMs) so that various properties (including ocean surface roughness, vegetation, soil moisture, and so on) can be retrieved. This paper describes not only the development of the NSPO GPSR but also the design, development, and special features of the Triton’s GNSS-R mission. Moreover, in order to verify the NSPO GNSS-R receiver, ground/flight tests are deemed essential. Then, data analyses of the airborne GNSS-R tests are presented in this paper.
