When You need PreCISIon, You need IPAdS

L-3 Space & Navigation (S&N)

Improved Position and Azimuth

Determining System (IPADS) is a

self-contained inertial surveying system developed to meet

today’s demanding U.S. Army and Marine Corps survey

needs. Survey operations functionality, navigational accuracy,

transportability, survivability and affordability requirements drove

the system design.

L-3 S&N’s IPADS provides significant enhancements for today’s

Army and Marine Corps survey teams. While meeting PADS

accuracy and environmental requirements, IPADS offers a proven,

reliable, lightweight, off-the-shelf solution developed around four

line-replaceable units (LRUs).

• Compact Position/ Navigation Unit (CPNU)

• Control and Display Unit (CDU)

• Battery and Charger Unit (BCU)

• Porro Prism Assembly (PPA)

All LRUs are housed in a

robust frame that allows for

easy component access and

stability while facilitating

ready, two-person transfer

between vehicles and aircraft.

FeAtureS

• High-precision common survey delivers efficient mass fires

• Impervious to jamming

• Resistant to jamming (GPS-aided mode)

• Navigation aids (compass rose and digital maps)

• In-vehicle survey

• Combat-proven

• Embedded built-in test (BIT)

• High reliability MTBF, low mean time to repair (MTTR)

• No periodic calibration required

ComPACt PoSItIon/nAvIgAtIon unIt (CPnu)

The CPNU, a three-axis strap-down inertial navigation system of ring laser gyros and high-grade accelerometers, is the core component of IPADS. It is the compact version of our proven navigation system used on the MLRS (Multiple Launch Rocket System) and HIMARS (High-Mobility Artillery Rocket System) programs.

ControL And dISPLAY unIt (Cdu)

IPADS uses the Tacter-31 Rugged Handheld Computer (RHC) as its CDU. This capitalizes on the existing logistics support coverage and provides significant life-cycle cost benefits. The RHC is a standard IBM® PC with an Intel® Pentium II 500 MHz processor, Windows® 2000, a 6.4-inch VGA color active matrix LCD display and a QWERTY keyboard. The CDU offers the Tactical Communication Interface Modem (TCIM) as an option.

Porro PrISm ASSembLY (PPA)

The PPA increases the IPADS’ 16-m offset capability by 50%. IPADS can also provide distance point (target) location capability with the use of optional accessories such as a hand-held laser rangefinder mounted on existing P2/P16 theodolites or a total system.

bAtterY And ChArger unIt (bCu)

The BCU uses a standard U.S. Army NSN 6130-01-493-6643 Sealed Lead Acid (SLA) battery. The BCU is based on the ABPAC.DC/BT-TR-1 Transceiver Power Unit (TPU) that is currently fielded by the U.S. military. The unit allows for worldwide input of 9 to 36 VDC / 85 to 270 VAC, 47 to 440 Hz, single-phase power inputs and provides power and charge status indicators.
