The LC 1x1 low‑cost GPSDO uses a single‑oven oscillator to deliver ±35 ns RMS 1 PPS accuracy when GPS‑locked, with holdover stability better than ±15 µs over 24 hours at 25°C after extended GPS conditioning. It provides RS‑232 control with NMEA and SCPI support and operates on the GPS L1 C/A 1574 MHz signal using an active or passive antenna. Its 50‑channel receiver supports SBAS systems including WAAS, EGNOS, and MSAS, with acquisition sensitivity of −142 dBm and tracking sensitivity of −158 dBm. TTFF is under 45 seconds cold and 1 second for warm or hot starts, with ADEV performance below 1E‑10 at 1000 seconds and 8E‑12 at 10,000 seconds.
