Invocon produces a variety of control, power and monitoring solutions for rocket and missile applications. These are flight qualified devices for safe and reliable control and monitoring of ordnance and various flight events. These include Multichannel Event Sequencers, Capacitive Discharge Initiator (CDI) Modules, Lithium Ion Polymer Smart Batteries, power controllers, and Kinetic Impact Position Systems. Below are some of the available technology profiles:
The Integrated PCM Encoder (iPCMe) provides a significant number of data channels for remote sensing and synchronous logging in a highly integrated configuration. With over 100 channels of input in a small package, the iPCMe is designed as a low-cost solution for a broad range of telemetry applications.

The iPCMe was used during CTREX rocket experiment in 2014. Click here for the summary of iPCMe use during the CTREX experiment.
The Distributed Impact Detection System (DIDS) was originally designed to detect and locate impacts on space vehicles. With a sample rate approaching 1 MHz on each of its four channels and its fast wake up capability, DIDS provides highly dynamic data. Since its initial application, its capabilities have been expanded to locate leaks in pressurized volumes such as the International Space Station. A low-frequency version (30 kHz) has also been installed in the Bigelow Expandable Activity Module (BEAM) aboard the ISS as a means to detect impacts from micro-meteoroids and orbital debris (MMOD).
The Tension Measurement System (TMS) was been utilized by the NASA X-38 project to make the first-ever load distribution measurements on a large-scale parafoil system during opening and free flight. The insight provided by TMS riser and leading edge load measurement has allowed NASA and Pioneer aerospace engineers to reduce the number of full-scale drops required to refine and qualify the X-38 parafoil system. NASA extended TMS data utilization to include extraction of aerodynamic coefficients and flight attitude histories from the X-38 parafoil system during parafoil flight and landing flares.
EWIS was developed to provide long-term structural dynamics measurements of the International Space Station (ISS).
IWIS, the internal, synchronized system, is deployed by the astronauts inside the partially completed ISS to collect data on the impulse response of the structure. This synchronized data is used to verify the structural integrity of the ISS on orbit. It will also be used to update models predicting the modal response of the ISS. Complete understanding of the resonant modes of the structure will allow effective planning of the re-boost and Reaction Control System (RCS) firing sequences when the Shuttle is docked with the Station. Since this data will change as the Station is assembled, it is important to keep this data current with each addition to the Station. The wireless nature of the data acquisition network minimizes the time necessary for deployment and recovery of the system. Further, some of the RCS test firings must occur when all airlocks between modules are closed. A wired system would not have the flexibility needed to accommodate mission changes and data acquisition windows of opportunity.
NASA installed 44 Enhanced Wide-Band MicroTAU (EWB MicroTAU) units in each of the last three Space Shuttle Orbiters to monitor the RCC panels on the leading edges of their wings. This system was developed for NASA to detect impacts from foam during ascent, and to detect Micro-Meteoroids and Orbital Debris (MM/OD) during space operation. The system flew on the final 22 flights of the Orbiter.
NASA utilized the Wide-Band Micro-Miniature Tri-Axial Accelerometer Unit, WB MicroTAU, to monitor a series of foam impact tests simulating the launch impact event on the Space Shuttle Columbia in early 2003. During this testing, 14 tri-axial units were located in and around the target articles and recorded impact signatures at 20,000Hz from each accelerometer.
The Micro-miniature Wireless Instrumentation (MicroWIS) System was used by a university in Houston, Texas, to study stresses on a local bridge during construction and testing. The application stemmed from concerns that a significant portion of a bridge’s useful life may actually be expended in the construction process due to inadequate support of its members during handling and installation.
The Micro-miniature Wireless Instrumentation System (MicroWIS) has been used to monitor external grout pressure during construction of multiple tunnels in the Netherlands. Grout pressure determines the amount of grout that is deposited on the outside of the tunnel and influences the amount of settling that occurs at the surface. This is critical for maintaining the integrity of both the tunnel and nearby structures.
The Multiple-Input Tiny, Enhanced Wireless Instrumentation System, MITE WIS, is currently being used to monitor repaired concrete sections of the Westerschelde Tunnel in the Netherlands. The MITE WIS units help detect problems in the repairs to the sections that have been covered by a layer of high-temperature fireproofing.
Invocon has provided NASA multiple solutions for applications ranging from instrumentation for prototype testing to vehicle health monitoring on the International Space Station (ISS) and on the Space Shuttle Orbiter.
