--- Quote ---"JOINT PRECISION APPROACH AND LANDING SYSTEM (JPALS) pp 28-29
Joint Precision Approach and Landing System (JPALS) is a GPS based system that will be the replacement for the current ACLS/SPN-46 system. Unlike the SPN-46 that uses radar on the boat to track an aircraft, JPALS works by comparing the GPS position of the carrier and the GPS position of the aircraft. A relative navigation (Rel Nav) solution is calculated and displayed as guidance in the cockpit. Initial tests were conducted in 2000 with an F-18 to prove that the concept worked. JPALS should IOC in 2014 and will start to be retrofitted on Hornets. H-60’s and E-2D’s should start to see it in 2017. It will be the only approach guidance on NUCAS (Navy Unmanned Combat Air System) and the F-35. Every carrier will be equipped by 2024.
How is it better? It will be GPS based and is jam resistant. Instead of an operator in CATCC having to lock up an aircraft with the SPN-46 radar, only a data link between the ship and aircraft needs to be established making the system more reliable. This link will be established when the aircraft gets within 200 miles of the carrier, not at 5 miles behind the ship prior to tip over. The linked Rel Nav solution will also act like a TACAN and give ships position out to 200 miles. The link transmission, like MIDS, uses spread spectrum transmissions so it does not give away position and can be used during EMCON conditions. Mode I approaches will also be more accurate. The SPN-46 radar loses the aircraft at the round down. Past the round down glide slope guidance is basically an average of the last few seconds of the flight path. That is why during a Mode I the hornet freezes control input commands in the last 2 seconds before touchdown. The JPALS GPS guidance will be accurate all the way to touchdown. The Air Force and Army are funding a ground based JPALS system that can be easily setup at any airfield giving the Hornet an actual precision approach besides a PAR.
How will it affect me? With no need for interaction with an operator in CATCC, JPALS may be available during Case I approaches providing better gouge through the approach turn then the ICLS. Drop locks at 3 miles should not be a problem anymore; if you have JPALS in Marshall you’ll have it on final. The pickle switch on the platform will be connected to the data link and transmitted to the aircraft providing a true “W/O” discrete in the HUD and the ability to wave off a UAV. The ships final bearing will also be automatically linked to the aircraft and instantaneously updated in the cockpit, greatly enhancing SA to which direction the ship is turning while we are trying to land.
The mechanization and cockpit displays are still in the design phase. Do we want it to look just like ACLS or ICLS? Is it going to be called needles, bullseye, or _______? Should final bearing automatically be set as a course line? Is there a better way than the old way to do business? As fleet operators and LSO’s if you have any suggestions or ideas please let us know. In a few years JPALS will be a great tool to help us get the Air Wing aboard safely."

Navy Completes Initial Development of New Carrier Landing System 22 Nov 2013 Dave Majumdar
--- Quote ---"The U.S. Navy has completed the initial development of the Joint Precision Approach and Landing System (JPALS), Naval Air Systems Command (NAVAIR) officials told USNI News.
The system is designed to aid pilots landing in inclement weather conditions and will eventually replace the current Instrument Carrier Landing System (ICLS) and the Automatic Carrier Landing System (ACLS) onboard the service’s aircraft carrier fleet.
“The current Engineering and Manufacturing Development (EMD) effort was completed this month with the highly successful shipboard autoland testing on USS Theodore Roosevelt (CVN-71),” NAVAIR spokeswoman Marcia Hart said in a statement provided to USNI News. The core of the JPALS technology is an extremely precise ship-relative GPS-based system which is much more accurate than the existing pilot aids onboard the carrier.
The Navy had tested the JPALS onboard the USS George Bush (CVN-77) earlier in July to verify the system’s capability to support manual landings. The latest testing onboard the Roosevelt was to demonstrate the system’s ability to support automatic “hands-off” landings on board a carrier.
For the Navy, the development of the JPALS is the huge step forward for integrating new aircraft into the carrier air wing. “Legacy systems cannot support UAS [Unmanned Air Systems], and [the Lockheed Martin Joint Strike Fighter] F-35 was designed with JPALS capabilities. JPALS Increment 1 is based on ship relative GPS technology,” Hart said.
While the initial development is now complete, the Navy still has work to do to finish all seven increments of the JPALS capability. The system will also eventually support flight operations onboard amphibious assault ships and U.S. Air Force airfields.
NAVAIR’s immediate focus however will be to continue developmental work for supporting the F-35C and unmanned aircraft onboard a carrier. JPALS is particularly important for the Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS) program.
While the Northrop Grumman X-47B Unmanned Combat Air System Demonstrator (UCAS-D) uses a similar prototype ship-relative GPS-based landing system technology, it is not the same system as an operationally deployable JPALS. “The program office continues development in support of the UCLASS and F-35 programs as well as multi-platform avionics integration,” Hart wrote.
The Navy will be the first service to field the new landing system on the F-35C. “Initial JPALS fielding is scheduled in support of F-35C first deployment,” Hart wrote. “However, sequestration and continuing resolution associated budget uncertainty will likely impact projected plans.”
Eventually, the USAF and the USMC will also use the JPALS for their operations."

Seems Strike Test is feeling the effects of budget cuts. The paint job leaves a lot to be desired, the drop tank belongs to VFA-154, and the driver is wearing his old helmet from VFA-2. Geez.
