Robust Design for GNSS Integration

James L. Farrell

Abstract:	Loss of satellite navigation data can be catastrophic in many operations. Common mechanization approaches often fail to provide adequate protection under adverse conditions. Remedial methods are largely based on refocusing of objectives – e.g., • aircraft with dozens of meters wingspan don’t have to be located to within 1-cm as they move at 400 kts, • In most operations, dependably providing continuous position to within a few meters is highly preferable to usually positioning within ± 1 cm. Means for full usage of partial data are more extensive in scope than generally realized – and some that are known have only recently become feasible through technological advances. Flight-validated methods described herein, inside and external to the receiver, remain applicable with or without IMU augmentation.
