Why wireless Auto-METAR

  • Minimizes building permits to enable quick and affordable installation of an airport weather monitoring system.
  • Airport and heliport weather station for small and private airports, heliports and airstrips for real-time VFR decision making. (IFR option available)
  • High system reliability is assured by the weather station's redundant power control/management system called PowerProtect with full lightning protection.
  • PowerProtect is designed to isolate sensor power faults and any unforeseen sensor electrical problems for high up-time and reliability.
  • METARlogGSM is the Auto-METAR generating unit. It is a field proven meteorological data logger and future-proof with very good expandability and upgradeability. 

Start small and grow

Basic sensor set for limited METAR report generation includes:

  • Wind speed & wind direction (available with heating for all-weather reliability in winter climates)
  • Temperature, humidity, dew/frost point
  • Barometric pressure - multiple options available
  • Wireless Auto-METAR transmission via GSM/GPRS for placement flexibility and to minimize cables and associated ground work and permits

Reliability & robustness

Proven reliable sensors tested in all climates featuring:

  • Heated wind sensor is optional for cold climates
  • Sensors feature 3-stage lightning protection
  • PowerProtect automatically disconnects electrical faults to maintain weather station up-time in case of electrical faults, short circuits or lightning strikes
  • Backup 12 V Pb (lead-acid) battery charging and monitoring of battery performance parameters for preventative battery replacement detection
  • ESD, EMI, surge, transient & lightning protection on all logger power and data lines

Expandability & growth

FUTURE PROOF High-accuracy triple redundant pressure sensor upgrade for IFR airports.

Future-Proof Sensor Expandability

  • Ability to add multiple high-accuracy barometric pressure sensors for redundancy and reliability to meet IFR airport requirements
  • Expandability is assured via fully independent digital sensor ports to suit specific airport requirements
  • Option to add a ceilometer for cloud base monitoring
  • Up to 8 total RS-485 MODBUS sensors
  • 2 fully independent sensor power branches/lines
  • Serial ASCII and MODBUS RTU interface to your existing infrastructure and software. 


At the heart of our Auto-METAR generating weather station for airports is the METARlogGSM real-time data logger & PowerProtect electrical management & protection system. Weather data from METARlogGSM can be directly fed into your existing servers and software system or on-line METAR widget on your website.
