FOS with PSS integrated: nowhere for the enemy to hide.
Major General David P. Valcourt David P. Valcourt is a Lieutenant General of the United States Army. He was previously the Commanding General of the Field Artillery Center and Fort Sill, Oklahoma. , then Chief of Field Artillery, said "Overcoming TLE TLE Temporal Lobe Epilepsy
TLE The Living End (band)
TLE Two Line Elements (for satellite tracking)
TLE The Learning Equation
TLE Taxe Locale d'Équipement [target location error], our bane for more than 30 years, will deliver the 'keys to the joint effects kingdom' to our observers." ("Crossed Cannons on Your Collar: Change and Opportunity--Steady in the Harness," March-June 2004). He was right.
With that charter and to respond to the warfighters' needs, we integrated the mounted forward observer system (FOS) and precision-strike suite (PSS See EPSS. ) application to overcome TLE. As a "joint reuse" effort, this allows the FO to use the joint PSS software on his hand-held digital device to locate targets precisely enough to execute them with precision-guided munitions (PGMs) or as close air support (CAS) missions. With PSS integrated into FOS, the FO at the tactical level can determine accurate coordinates in just seconds vice waiting much longer for target "mensuration mensuration /men·su·ra·tion/ (men?ser-a´shun) the act or process of measuring. " at much higher levels.
The FOS-PSS integration gives the FO the option of employing the integrated software when executing PGMs or employing the original FOS. The target area resolution of FOS (only) has been decreased significantly. FOS now provides a one-square-meter resolution vice its former 10-square-meter resolution.
Completely understanding what this integration means to the joint warfighter requires revisiting the capabilities of each application.
FOS. This is a system developed by the Fire Support Software Engineering Division, Communications and Electronics Command (CECOM CECOM Communications Electronics Command (US Army)
CECOM National Center for Communications of the Civil Protection Agency ), located at Fort Sill, Oklahoma, to be the primary support for FOs, fire support teams (FISTs), FA commanders, fire support officers (FSOs) and survey teams in their mission areas. FOS provides automated capabilities in both mounted and in limited dismounted configurations. As a mounted integrated subsystem, it is a critical to the Bradley fire support team (BFIST BFIST Bradley Fire Support Team (M7 Bradley Fire Support Vehicle crew) ), Knight, Stryker and combat observation lasing team (COLT) vehicles.
FOS interfaces with the advanced FA tactical data system (AFATDS AFATDS Advanced Field Artillery Tactical Data System (US Army)
AFATDS Army Field Artillery Tactical Data System (US Army)
AFATDS Air Force Airborne Tactical Data System (USAF) ) and weapon systems through a standardized signaling and messaging protocol set while maintaining compatibility with legacy systems via legacy signaling and messaging protocols. FOS also maintains a direct link with maneuver's Force XXI battle command brigade and below (FBC[B.sup.2]) to clear fires in the fire support mission chain. FOS processes and translates this mix of data types and then sends it to the tactical operations center A physical groupment of those elements of a general and special staff concerned with the current tactical operations and the tactical support thereof. Also called TOC. See also command post. (TOC) and weapon platforms. This extensive interface network is shown in the figure.
FOS initially was developed during the late 1980s before the emergence of self-locating FA platforms or PGMs and before we had joint FOs (JFOs) helping joint terminal attack controllers (JTACs) control aircraft dropping precision ordnance in Types 2 and 3 CAS. In addition, our forces now operate in an urban environment with a high density of innocent civilians, calling for very accurate target locations--one round per target. These requirements exceed the accuracy and target resolution capabilities of previous observer devices.

PSS. The Naval Weapons Center at China Lake, California, developed the PSS application. The National Geo-spatial Agency (NGA) at Bethesda, Maryland, has approved and validated PSS as a tool for determining precision geospatial coordinates. PSS prepares image datasets, called the digital point positioning database (DPPDB DPPDB digital point positioning database (US DoD) ), to pull precise geospatial coordinates for target engagement. These classified image datasets are available to the unit from NGA on DVD DVD: see digital versatile disc.

For the last several years, PSS has enjoyed much success, primarily with Special Operations Forces Those Active and Reserve Component forces of the Military Services designated by the Secretary of Defense and specifically organized, trained, and equipped to conduct and support special operations. Also called SOF. (SOF) employing it in Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF). The Joint Forces Command (JFCOM JFCOM Joint Forces Command (formerly ACOM change effective 1 Oct 99) ), headquartered at Norfolk, Virginia, sponsors PSS and has worked with the services to integrate the capability into each of the appropriate CAS suites used by SOF and conventional JTACs.
The PSS application gives extremely tight resolutions using stereoscopic images with a point-and-click target-location capability. NGA has preprocessed these images into three-dimensional resolutions. This allows the trained FO to see a static top-down omni-view of the target location that is accurate enough--in some cases more than accurate enough--to employ all current and planned precision fire-and-forget munitions.
PSS also augments FOS' capabilities with fragmentation rings definable by the user to determine the danger zones and potential for collateral damage before the munitions are fired. This allows the FO to conduct a collateral damage estimate (CDE (1) (Computer Desktop Encyclopedia) What you are reading at this very moment. See About this product.

Integrated Capabilities. As a result of prototyping FOS with PSS-SOF PSS-SOF Precision Strike Suite for Special Operations Forces , the Fire Support Software Engineering Division contacted China Lake and JFCOM in June 2005 to enter into a joint reuse effort for the PSS software. The Fire Support Software Engineering Division's integration effort began on 1 November 2005. The integrated system completed qualification testing on 13 January 2006.
The integrated FOS-PSS software will be released to OIF and OEF rotational units in the Second Quarter of FY07, potentially coinciding with the fielding of the 155-mmExcaliburunitaryPGM. (See the article "FA PGMs--Revolutionizing Fires for the Ground Force Commander" in the May-June edition online at sill-www.army.mil/famag/index.asp.)
FOS is already being incorporated into the JFO Course taught at Fort Sill. This facilitates Types 2 and 3 CAS. The JFO Course will certify the JFOs on PSS, based on NGA certification standards.
The FOS and PSS integration brings significantly reduced TLE and increased support for collateral damage assessment. This integration uses FOS' extensive interface, communications and messaging capabilities to provide a verified unbroken digital message chain from the observer through command and control systems to the weapons delivery platforms. The integration provides a resolution and accuracy more than sufficient to employ all PGMs with a standard of 90 percent circular error (CE) and lateral error (LE).

This facilitates AFATDS' clearance of fires processing through all AFATDS nodes before the fire mission is sent to the delivery platform, which factors in additional information, the commander's pre-programmed guidance and battlefield and higher level insights.
With "hands-free" communications already established, the FO can use this system to send all artillery or mortar munitions down range onto the specified targets in 30 seconds or less after the mission is initiated. Because the FO can locate the target precisely in seconds, it decreases the time it takes to clear fires and execute air-dropped or FA precision munitions. This decrease in clearance time, in part, is due to the CDE's being passed by the FOS integrated system through AFATDS to the targeting cell.
Using FOS-PSS, the stationary FO can locate his own position as precisely as he can the target's position. The FO can determine a precise enough location to calibrate his laser.
The integrated FOS displays a static daylight image of the area of operations An operational area defined by the joint force commander for land and naval forces. Areas of operation do not typically encompass the entire operational area of the joint force commander, but should be large enough for component commanders to accomplish their missions and protect their (AO) at night. It helps the survey teams with initial location accuracy and serves as a quick check point for survey calculations and procedures.
The integrated system operates on the ruggedized handheld computer (RHC) and the standalone computer unit (SCU). Due to the system's size and processing demands, the integrated FOS and PSS won't work on the existing handheld terminal unit (HTU) and lightweight computer unit (LCU). PSS will not load on these platforms with FOS installed.
In the future, the integrated FOS user will have dynamic, highly accurate scene matching using near-real-time images from a variety of sources, such as commercial satellite images (recently validated by NGA). The scenes, without the associated error terms, have approximately the same accuracy as the static images currently used with PSS.
The improved FOS without PSS is very accurate for locating targets and the FO's position to employ conventional munitions. But when using PSS integrated into FOS, the FO can employ the fire-and-forget PGMs 24/7 in all weather conditions and respond very rapidly with the effects the ground force commander needs. FOS with PSS truly has delivered the keys to the joint effects kingdom to our FOs.
