Radio Altimeters

A radar altimeter (RA), radio altimeter (RALT), electronic altimeter, or reflection altimeter measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft.

TACAN Test Systems

A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system used by military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne station.

Optical Light Sources

A fibre light source is used to inject light into a fibre optic cable for the purpose of testing it. They come in two basic varieties: light emitting diodes (LEDs) and laser diodes. They’re further differentiated by the wavelength they produce and the type of cable they test.

Optical Power Meters

Fast, cost-effective and easy-to-use power meters for installation and maintenance of single mode and multimode fiber optic networks and advanced, photonic-layer power meters for lab and production environments.

Visual Fault Locators

A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects.

Spectrum Analysers

A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.

GPS Simulators

As GPS receivers are built into more mission-critical devices for difficult application environments, and designed with the emerging capabilities of a multitude of GNSS constellations and augmentation systems, developers and manufacturers need better ways to guarantee performance. That’s where GPS signal generation comes in.

Global Navigation Satellite System or GNSS is the term for satellite navigation systems that provide positioning with global coverage. A GNSS allow small electronic receivers to determine their location (longitude, latitude, and altitude) to within a few metres using time signals transmitted along a line of sight by radio from satellites.
