Symphonie® iPackGPS | Iridium

Automate the transfer of measurement data from the project site to your desktop through the Iridium satellite network.

  • Symphonie® iPackGPS | Iridium

Configuration Options

Symphonie iPackGPS (Iridium) is an internet-enabled communications and autonomous power module for Symphonie series data loggers (models SymphoniePLUS3 and older). Utilizing a satellite modem that connects SymphoniePLUS®3 Data Logger to the Iridium satellite network, iPackGPS delivers collected data to your desktop anywhere in the world.

Why Iridium?

The Iridium satellite service was carefully selected by NRG for its comprehensive and reliable reach. The Iridium network covers the entire planet, including the poles and oceans.

Data Logger Connection

iPackGPS attaches to a port located on the back of the SymphoniePLUS3. The iPackGPS and the data logger are then secured to a Symphonie shelter box using four screws.

Power Supply

iPackGPS (Iridium) contains two rechargeable 12V sealed lead-acid batteries and a recharging circuit. The recharging circuit is designed for use with an external 15W PV panel, which connects to terminals on the side of the iPackGPS. Terminals for an external power system are also available. This configuration keeps the internal batteries continuously charged—ensuring reliable data logging and transfer operations.

Accounts and Programming

iPackGPS (Iridium) comes bundled with 400 minutes of satellite airtime and access to a dedicated email service, WindLinx (account activation form included). WindLinx is a worldwide service that streamlines account setup and the overall management of data transfer from multiple sites. Once an account is created, the satellite transceiver inside the Symphonie iPackGPS can be activated and configured with supplied settings.
