With the ability to receive up to three GNSS systems concurrently, the Microsemi GPS-3xx0 devices are the preeminent solutions for demanding mobile GNSS applications. Their height of 1 inch makes them ideal for applications such as military manpack radios, MILSATCOM terminals, avionics payloads for unmanned autonomous systems (UAS), and high-acceleration applications, such as jet fighters. All of these applications are increasingly expected to deliver mission-critical performance, even in GNSS-denied environments. Other applications include network timing in stationary applications, such as basestations. The GPS-3550, GPS-3500, GPS-3300, and GPS-3100 are 10 MHz MAC-based GPS-disciplined oscillators (GPSDOs). They cover a temperature range of –20 ºC to 70 ºC, measured at the baseplate. These products utilize Microsemi’s series SA.3Xm Miniature Atomic Clock (MAC) as their frequency reference, which enables unparalleled holdover capability, best-in-class Tempco, and a very fast warmup time of <8 minutes. The builtin high-performance GNSS receiver can operate in a base station positionhold mode using an auto survey feature, which allows operation with just a single satellite in view, thereby improving timing stability. Key Features High-performance GNSS receiver Unparalleled holdover: typically ±0.6μs over 24 hrs. at 25 ºC (GPS-3500) Low power consumption: less than 5.6W at 25 ºC Ultra-low noise post filter crystal Industry leading 1PPS accuracy: ±10ns to UTC RMS (1-sigma), GPS locked Small footprint and low profile: only 3.4" x 4.4" x 1"
