Core Avionics Master Plan 2011 Appendix A-32. Advanced Research and Technology Development.Military Space Signal & User Equipment Enhancements. (2010-2012) The GPSWing is managing design and development of MGUE to use the next generation GPSsignal, M-Code. Simultaneously, they are leveraging commercial advancements withGPS antennas and electronic packages. Cell phone and automobile applications havedriven GPS UE size and weight reductions. Digitization of components is providingcleaner processing and allowing elimination of noise interference. Faster processingcan eliminate latency issues in fast moving aircraft. These enhancements areconsidered critical to meet weight, size, sensitivity and reliability threshold specificationsfor unmanned aerial vehicles. Improvements in the RAIM algorithm to an AdvancedRAIM (ARAIM) algorithm will allow tactical aircraft to achieve LPV capability using PPSGPS receivers because of improvements in vertical accuracy, integrity and availability.3. Funded Enhancements and Potential Pursuits.Digitally Augmented Ship Approach Sequencing (JPALS). (2015) JPALS willprovide for increased ship to aircraft relative position accuracy to support ship recoveryoperations using Shipboard Relative GPS (SRGPS). After launch and during recoveryoperations, aircraft will utilize datalink information on ship position and altitude toestablish more efficient aircraft marshalling procedures and approaches to the ship‟sExpected Final Bearing (EFB). The SRGPS link between the ship and the aircraft on theEFB will enable the aircraft to achieve a very precise lateral and vertical approach to theship in all weather and all tactical conditions minimizing aircraft recovery time duringflight operations. Utilization of tighter patterns has already demonstrated time and fuelsavings in commercial airport operations, and should provide similar benefits in carrierand multi-spot amphibious ship operations. JPALS precision navigation will require 24channel GPS receivers that manipulate both L1/L2 PPS GPS signals.Digital Airfield Sequencing (JPALS). (2018) Aircraft that are configured withJPALS will be able to immediately take advantage of improved approach sequencingwhen JPALS units are established at shore bases. Shore based JPALS at military airstations will utilize one way military unique datalink information for GPS augmentation toprovide civil equivalent precision approach capabilities. Land based JPALS will alsoprovide civil GPS augmentation to enable naval aircraft to have access to civil (GPSaugmented) precision approach procedures.C. Information Media. This capability element refers to paper and electronicnavigation information media formats.1. Current Capabilities.Although mission planning systems for several platforms have incorporated thecapability to upload geographical data to support mission accomplishment, most usersare still using paper charts for primary means of navigation. The National GeospatialIntelligence Agency (NGA – formerly the National Imagery and Mapping Agency)provides DOD Flight Information Publications (FLIP) consisting of Enroute and terminalnavigation charts, General Planning (GP), Area Planning (AP) and other flightInformation publications for military aviators in paper and digital formats (online PDF orother graphic formats). Digital Aeronautical Flight Information Files (DAFIF) is the NGAA-3 Navigation 6
