A Chip-Scale Atomic Clock (CSAC) provides the necessary precise and stable timing where traditional atomic clocks are too large or power-hungry and where other satellite-based references may be compromised.

Microchip has developed the Evacuated Miniature Crystal Oscillator (EMXO) technology and integrated it into a CSAC, enabling the model SA65-LN to offer a reduced profile height of less than ½ inch, while maintaining a power consumption of < 295 mW. The new design is optimal for aerospace and defense mission-critical applications such as mobile radar, dismounted radios, dismounted IED jamming systems, autonomous sensor networks and unmanned vehicles due to its compact size, low power consumption and high precision. Operating within a wider temperature range of −40°C to +80°C, the new LN-CSAC is designed to maintain its frequency and phase stability in extreme conditions for enhanced reliability.

“A significant advancement in frequency technology, our next generation LN-CSAC provides exceptional stability and precision in a remarkably compact form,” said Randy Brudzinski, corporate vice president of Microchip’s frequency and time systems business unit. “This device enables our customers to achieve superior signal clarity and atomic-level accuracy, while also benefiting from reduced design complexity and lower power consumption.”

The LN-CSAC combines a crystal oscillator and an atomic clock in a single compact device. The EMXO offers low-phase noise at 10 Hz < −120 dBc/Hz and Allan Deviation (ADEV) stability < 1E-11 at a 1-second averaging time. The atomic clock provides initial accuracy of ±0.5 ppb, low frequency drift performance of < 0.9 ppb/mo, and maximum temperature-induced errors of < ±0.3ppb. Together, the LN-CSAC can save board space, design time and overall power consumption compared to designs that feature two oscillators.

The crystal signal purity and low-phase noise of LN-CSAC are designed to ensure high-quality signal integrity, which is essential for frequency mixing. The atomic-level accuracy allows for longer intervals between calibrations, which can help extend mission durations and potentially reduce maintenance requirements.

HydroGNSS is one of a series of ESA missions, the so-called Scout missions, part of the agency’s FutureEO program, designed to quickly and cheaply demonstrate new Earth observation techniques using small satellites.

GNSS signals are differentially reflected or scattered by the Earth’s surface, as affected by water content, specifically permittivity, surface roughness and overlying vegetation. Once analyzed, these reflected signals can provide information about various geophysical properties. Special innovations introduced by HydroGNSS are to include dual-polarization and dual-frequency (L1/E1 and L5/E5) reception, and collection of high-rate coherent reflections.

Compact but powerful Earth observation platform

HydroGNSS uses the SSTL-21 platform, measuring 45 cm x 45 cm x 70 cm and weighing around 65 kg total per satellite. The payload will be operated at near 100% duty, and can support high data download rates using an X-Band transmitter. Star cameras provide precise attitude measurements, and a xenon propulsion system permits orbit phasing, collision avoidance and supports satellite disposal at the end of the mission. The two HydroGNSS satellites will take a ride-share launch into a 550 km sun-synchronous orbit, phased apart by 180 degrees to maximize coverage.

The SGR-ReSI-Z payload is a delay Doppler mapping receiver, tracking the direct GPS and Galileo signals through a zenith antenna and processing the reflected signals from a nadir antenna to create delay Doppler maps (DDMs). The zenith and nadir antennas employ all-metal patch technology, enabling the reception of dual-frequency and dual-polarized signals. Low noise amplifiers include blackbody loads to provide calibration for the amplitude measurement. Generated measurement datasets can be stored in the satellite’s data recorder and downloaded to ground stations at allocated passes several times per day.

Speaking at his annual press briefing in Paris earlier this month (January 2025), ESA Director General Joseph Aschbacher said, “We now expect to launch HydroGNSS in the fourth quarter of 2025, as one of the three so-far-identified Scout missions, which is a series based on smaller satellites, lasting three years of development work and with a relatively limited budget of roughly 30 million for industrial contracts. We see the Scout missions as something very important for our space science work. The scientific community is evaluating them and these are the ones selected and endorsed by them.”

GNSS signal jamming is a considerable threat in today’s unstable geopolitical environment. Almost everything we count on today depends on GNSS PNT, including communications, transportation, agriculture, the Internet and banking.

To stay ahead of the jamming threat, affordable, practical and easily implementable solutions are required. The new GAJT-310 provides users with the latest powerful anti-jam technology with low latency in a smaller device. Low latency means the GAJT-310 can be put to work protecting signals immediately —no additional setup—just plug in and protect.

“The GAJT portfolio of tried and tested anti-jam technology can now protect all platforms,” stated Stig Pedersen, executive vice president of aerospace & defence at Hexagon’s Autonomy & Positioning division. “GAJT-310 is ideal for space-constrained and cost-sensitive platforms, including uncrewed or autonomous vehicles and UAVs.”  

What sets the GAJT-310 apart from other low SWaP options:

• Flexible and cost-effective – it is available as an integrated enclosure or federated option with separate electronics card and CRPA (Controlled Reception Pattern Antenna)
• Protection for more GNSS signals – on the L1 and L2 bands
• Commercially exportable technology – making the GAJT-310 accessible worldwide 

“We’ve taken everything we learned from the successful in-theatre deployment of the GAJT-710 and GAJT-410 for NATO forces worldwide and built it into the GAJT-310,” stated Neil Gerein, vice president of product, aerospace & defence at Hexagon’s Autonomy & Positioning division. “Regarding assured positioning, navigation and timing, we believe every platform in any industry should be protected.”
