ASTmidi GPS + A

STREET LIGHTING CONTROLLER WITH EXTERNAL GPS ANTENNA

ASTmidi GPS + A is an advanced astronomical street lighting controller equipped with an external GPS antenna, designed for reliable and fully automatic control of outdoor lighting systems. The external antenna ensures accurate time synchronization and GPS positioning, even in demanding installation environments.

Using GPS technology, the controller automatically determines its geographical position and calculates the optimal switching times for street lighting. Installation is quick and straightforward—simply connect the power supply and controlled circuits, and the controller automatically configures its operating parameters.

Designed for installation on a standard 35 mm DIN rail, the controller occupies only 3 DIN modules, making it an ideal solution for both new installations and retrofit lighting control cabinets.

Features

ASTmidi GPS incorporates all the capabilities of the AST controller family while offering additional functions that enhance configuration flexibility and operational efficiency.

The controller is available with 2 or 3 independent relay outputs (the third output is optional), includes a photocell/cascade input, and features integrated Bluetooth communication for wireless configuration using a mobile application.

The controller automatically:

  • synchronizes its internal clock with GPS satellites,
  • determines the installation location,
  • calculates astronomical sunrise and sunset switching times,
  • automatically adjusts for daylight saving time,
  • eliminates manual configuration of location and time.

Internal or External GPS Antenna

ASTmidi GPS is available in two hardware versions:

  • Internal GPS antenna – suitable for most standard outdoor lighting cabinets.
  • External GPS antenna – recommended for installations inside buildings, electrical rooms, metal enclosures, or any location where GPS reception may be limited.

A high-sensitivity 72-channel GPS receiver provides fast satellite acquisition and reliable time synchronization, ensuring accurate operation under challenging installation conditions.

ASTmobile – Wireless Configuration and Management

ASTmidi GPS is fully compatible with the free ASTmobile Android application.

The integrated Bluetooth interface enables complete wireless configuration without opening the control cabinet or using programming cables.

Using ASTmobile, users can:

  • monitor the controller status,
  • modify operating parameters,
  • display the installation location on a map,
  • synchronize controller settings,
  • save and restore configurations,
  • review the event history,
  • manually activate relay outputs for maintenance,
  • update the controller firmware wirelessly.
