Microsemi announces thermally improved chip-scale atomic clocks

Microsemi Corporation has announced its new thermally improved chip-scale atomic clock (CSAC) components with full operating and storage temperature. The new devices offer low-power holdover atomic clock technology without compromising size, weight and power (SWaP) while operating at a wide temperature range.

Microsemi is exhibiting this week at ION GNSS+, being held in Portland, Oregon.

With an operating temperature range of -10 to 70 degrees Celsius, Microsemi’s new CSAC components are highly reliable, with improved product design, process enhancements and robust product verification/validation, the company said.

The revolutionary technology enables new applications and missions not possible in the past with traditional OCXO and Rubidium clocks, offering the low SWaP clock technology at 17 cubic centimeters (cc) in size, 35 grams of weight and only 120 milliwatts of power. Microsemi’s CSAC product offers ±5.0E-11 accuracy at shipment and a typical ≤ 9.0E-10/month aging rate, which makes it suitable for many low-power atomic clock holdover applications.

“The enhancements to our CSAC product offering focus on providing the highest reliability without compromising performance for our customers, particularly in mission critical applications where every milliwatt matters,” said Ramki Ramakrishnan, director of product line management, at Microsemi. “These devices utilize an innovative approach to the component level atomic clock that will help Microsemi access the entire oscillator industry, along with miniature atomic clocks (MAC), and capitalize on the revenue growth potential within the defense, communications, industrial and test and measurement markets.”

According to the “Crystal Oscillator Market—Global Forecast & Analysts” report posted by Markets & Markets, the total available market (TAM) for the overall oscillator market is estimated to be $2.4 billion in 2016, with OCXO markets targeted by CSAC estimated to have a serviceable addressable market (SAM) of $260 million in 2016.

Microsemi’s thermally improved CSAC products support the company’s strategic presence in the defense and security markets, targeting applications such as low-power holdover against GPS vulnerabilities for position, navigation and timing security. They are also suitable for holdover in underwater (ocean bottom nodal) applications and atomic frequency reference in test and measurement applications.

“Leveraging the unique attributes of Microsemi’s CSAC technology, our company is able to offer an unprecedented combination of holdover, g-sensitivity, low power consumption and warm-up performance, while reducing the footprint to less than the critical 0.6 inches height — allowing retrofitting of legacy equipment,” explained Said Jackson, president of Jackson Labs Technologies, Inc. “The CSAC combined with our battle- and theater-proven software algorithms and support hardware enables vastly extended mission times while providing critical backup performance for GPS-denied environments when even the optional integrated Selective Availability Anti-spoofing Module (SAASM) GPS technology is jammed.”

Microsemi’s thermally remediated CSAC components are sampling now, with full production in October. For more information, visit the website or contact [email protected].

Launchpad: Dynamic testing before flight
GNSS/INS Integration Testing

Dynamic testing before flight

The CAST-3000 simulator from CAST Navigation.

The CAST-3000 fully supports integration testing of GNSS/INS navigation systems where the inertial sensor and GNSS receiver are either tightly or ultra-tightly coupled. It produces GPS RF signals coincident with simulated IMU sensor data that provide dynamic testing in the laboratory environment for military and government applications.

The proprietary laboratory test interfaces to inertial navigation products of both Honeywell and Northrop Grumman are incorporated with high-performance fighter aircraft and munition dynamics. The CAST-3000 simulates dynamics for both the GNSS and INS portions of EGI (embedded GNSS-inertial navigation) systems in a coordinated and coherent way so that the GNSS and INS navigation solutions do not diverge, and the blended solution is precisely what it would be in the real world. This is accomplished by simulating both the GNSS and INS inputs.

The military and government labs that the CAST-3000 supports have strict requirements for dynamic ground testing of navigation systems before flight testing. The simulator must explore performance of both GNSS and INS aspects of the EGI for modeling IMU drift rates in GPS jamming environments.

CAST-3000 Features
- Strapdown IMU measurement data synchronized with GPS RF data provided to the navigation system under test.
- Mature avionic sensor simulation barometric altimeter model.
- High-rate inertial measurements with very high degree of fidelity to support testing of high performance coupled systems.
- Simulates sensors to provide the fully coordinated, dynamic vertical channel aiding needed to maintain Kalman filter stability of the navigation system. Includes years of development and refinement of the precise GNSS/INS synchronization capability needed for simulation of aircraft dynamics.
- A dynamic, precisely coordinated simulation of numerous navigation signals to a tightly coupled or ultra-tightly coupled GNSS/INS navigation system.
