Dynamic INS and GNSS Signals

When you are faced with the challenging task of integrating and testing today’s complex EGI and GNSS/INS navigation systems, CAST Navigation’s INS system supports you by providing high rate inertial data with exceptional fidelity. We designed the system for optimal performance when the inertial sensor and GNSS receiver are loosely, tightly, or ultra-tightly coupled, or when an INS aiding source can be utilized by any other type of device.

CAST Navigation’s INS simulation systems provide the precise dynamic INS and GNSS signals you need to properly stimulate modern integrated navigation systems and platforms during development, integration, and testing. Our global clients include military, industrial, and commercial laboratories and we continue to play a critical role in their research and design of emerging technologies.

Intuitive GUI

CAST Navigation’s INS systems include a comprehensive and intuitive graphical user interface that enables you to customize the IMU sensor block’s output performance characteristics and drift rates to match those of your navigation unit or your performance modeling parameters. CAST systems also allow you to select from a wide variety of vehicle types: airborne, terrestrial, aquatic (including sea state), and space-based orbital vehicles. You can operate the systems in pre-generated or real time 6-DOF input motion generation modes and use them as a stand-alone or integrated into a “suite” of capabilities.

Inertial System Features

Systems are designed to provide precise dynamic signals for stimulation of modernized EGI and GNSS/INS devices in a laboratory environment
Operates as a stand-alone system or can be integrated into a laboratory environment to provide stimulus, based on 6-DOF trajectory data received
Provides an accurate synchronized simulation of navigation signals to loosely, tightly, and ultra-tightly coupled signals to stimulate EGI and GNSS/INS systems
Customizable and expandable solutions allows configurationof your GNSS/INS system to meet current and future requirements

Additional Inertial Outputs or Jamming Capabilities

For 40 years, CAST has collaborated with many IMU manufacturers in the development and refinement of laboratory test interfaces. CAST INS interfaces support most types of INS protocols and data rates and will customize an INS interface to meet specific requirements and testing needs.

The CAST INS modular design approach allows the technology to be combined with any CAST GNSS simulator and capability. We can configure these comprehensive and flexible systems to meet your changing or growing INS stimulation needs. We can easily add inertial outputs, RF outputs, and jamming capabilities to our system to meet you unique needs. We can also configure each additional output to provide identical, similar, or different IMU performance conditions, vehicle types, trajectories, and navigation signals.

We can modify any of our INS simulators to accept the addition of a variety of options—including additional signal, terrain obscuration, and signal interference capabilities—or synchronize multiple CAST systems to create a more robust and flexible simulation environment, to meet any specific or challenging application you may have.
