gps data loggers

Kingmach has been building monitoring instruments long enough to know that a general-purpose GPS data logger often misses the mark on job sites. Their GPS data loggers are part of a broader geotechnical range and are tuned for long-term autonomous recording. Each logger accepts L1/L2 or multi-frequency signals, depending on the model, and supports logging intervals from 1 second up to several hours, configurable through a simple text file or over a serial terminal. Compatibility is central to the design: the loggers output industry-standard RINEX 2.x and 3.x files, so they slide into Trimble Business Center, Leica Geo Office, or open-source packages like RTKLIB without conversion scripts. The onboard memory is typically a removable industrial-grade SD card, 32 GB or larger, which holds months of high-rate data. For live telemetry, a built-in 4G modem or LoRa radio module can be ordered at production time; Kingmach pre-configures the device for your local bands and carrier. Power consumption is low enough for solar-only setups, and the wide 9–36 V DC input protects against typical field power spikes. The enclosure is milled aluminum with IP66 sealing, and the antenna connection uses a rugged TNC or N-type bulkhead. Kingmach also handles customization without months of lead time — different antenna splitter configurations, additional sensor inputs (MEMS tilt, external meteorology), or custom cable lengths are standard requests. Technical support comes directly from engineers who know the firmware architecture, and there is a growing network of distributors that can provide hands-on assistance in your region. For engineers who need raw GNSS data that their post-processing pipeline can trust, these loggers avoid the lock-in and monthly fees that some competing trackers force.
