Trimble and Microsemi GPS/GNSS timing units
Every synchronised base station on a site ultimately traces its clock back to a GPS or GNSS timing receiver, and when that receiver fails the whole site can lose sync even though every radio is working normally. Buyers usually need either a smart antenna to replace a weathered or lightning-damaged unit, or a grandmaster clock — a Trimble Thunderbolt or Microsemi TimeProvider — that provides PTP or NTP timing to a whole site or exchange.
How to read these part numbers
Trimble's Acutime family are combined GPS antenna and receiver units mounted outdoors with a cable run to the equipment room; Thunderbolt and Resolution SMT are receiver/oscillator modules for indoor mounting with an external antenna. Microsemi's TimeProvider range are rack-mounted grandmaster clocks, numbered by generation (2300, 2700, 4100, 5000) with higher numbers generally meaning more capacity and IEEE 1588 PTP support; SyncServer units add NTP serving at volume alongside GNSS timing.

Ordering notes
State whether you need an outdoor smart antenna (Acutime) or an indoor receiver with separate antenna (Thunderbolt, Resolution SMT), and the maximum antenna cable run if outdoor — timing accuracy depends on correct cable delay compensation, which we will flag if your run is unusually long. For grandmaster clocks, confirm whether you need PTP, NTP or both. Condition is stated per quotation — new, new-surplus or refurbished — and where a destination does not admit used network equipment (Algeria is the usual example) we quote new. Hardware only: software licensing remains between the buyer and the manufacturer. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.
Lifecycle and availability
Current Trimble Acutime GG and Resolution SMT 360 remain in production; older Acutime 360, Acutime 2000 and Palisade units are supplied refurbished. Microsemi's TimeProvider 5000 and SyncServer S600/S650 are current production; TimeProvider 1100/2300 are increasingly surplus-only as networks migrate to PTP-capable grandmasters.
Equipment condition
New — factory-sealed, supplied through the manufacturer's own channel or a qualified distributor, with full manufacturer warranty.
New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.
Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.
Condition is confirmed in writing on every quotation before you commit to an order.
Warranty
Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.
Where equipment is supplied new through the manufacturer's own channel, the manufacturer's warranty applies and is passed to you.
Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.
Questions
Frequently asked questions
What is the difference between a GPS smart antenna and a GPS-disciplined clock?
A smart antenna like the Acutime combines the GNSS receiver and antenna in one outdoor-mounted unit and outputs timing signals over a cable; a disciplined clock like Thunderbolt takes a separate antenna feed and adds an oscillator and distribution outputs indoors. Which you need depends on your existing site design — tell us what is failing and we will match the replacement.
Do these units need line-of-sight to satellites specifically, or just outdoor mounting?
GNSS antennas need a clear view of open sky, not a specific satellite — obstruction from nearby structures is the most common cause of poor GPS timing performance on urban sites, and we can advise on antenna placement if that is the issue.
Can a Microsemi TimeProvider replace a Trimble Thunderbolt in the same role?
Functionally, for basic GPS-disciplined timing, often yes — but confirm your site's specific PTP/NTP requirements and rack space, since TimeProvider units are generally higher-capacity rack-mounted grandmasters rather than a like-for-like Thunderbolt replacement.
