Performance of a Prototype Local Area Augmentation System (LAAS) Ground Installation

Mats Brenner, Paul Kline, and Randy Reuter

Abstract:	The FAA released the Local Area Augmentation System (LAAS) Ground Facility (LGF) specification in 2001. This specification defines the requirements for precision landing in the United States. Honeywell has previously developed, certified and fielded a Special Category I Landing System, the SLS 2000. The successor, the SLS 3000, is the LAAS landing system currently under development at Honeywell International. The challenge in this development is to meet very stringent limits on the pseudo range correction error occurring due to a number of error sources such as signal deformation, RFI and insufficient power described in the FAA LGF specification. This paper presents prototype field data from each monitor function and compares it to synthetic data generated by modeling multipath, thermal noise, RF interference and other phenomena that affect the quality of the measured pseudo ranges used to calculate the broadcast differential corrections. The feasibility of LAAS is demonstrated by showing that good margins can be obtained in these monitors with the technology employed in the SLS 3000.
