Abstract:	This report addresses several issues important to the development of a Tactical Joint Precision Approach and Landing System (JPALS). These issues include: - Ground system siting and its impact on system startup time - JPALS/LAAS/GBAS interoperability with respect to siting - Flight inspection considerations - JPALS self-survey considerations The report finds that a tactical JPALS system can meet the performance requirements at system start-up provided that the multipath environment surrounding the ground facility is well-controlled and free of objects within a specified radius. The size of this object-clear zone radius increases by a factor of 10 if the JPALS system is to support Local Area Augmentation System (LAAS) operations using only C/A code. The report also finds that JPALS flight inspection procedures will be similar to those developed for the Mobile Microwave Landing System (MMLS) and LAAS. Finally, the report address several factors impacting a self-survey functionality imbedded in the JPALS ground facility.
