Because all GS sensors are "smart" sensors and have their own microprocessor and memory storage, it is possible to install them on site as stand-alone measurement devices without installing a GS-Logger at the base of the tower.   

  

There are a couple different ways to deploy GS sensors as stand-alone measurement devices.  The first is to install the sensors and booms on the tower, connect the sensors to the GS-Pod(s) without using a GS-Logger at all.  At the end of the measurement period, the GS-POD or GS sensor can be removed from the tower and connected to the GS-PAD to download the data.  Any non-GS sensors connected using a GS-ASIM will rely on the GS-ASIM for data storage, so in this case it is the GS-ASIM that is connected to the GS-PAD to download the data.   

  

The major drawbacks to using the GS sensors without a GS-Logger are:

 

1)  loss of real-time boom adjustment utilizing orientation and verticality features (detected by the logger communicating with the sensor and GS-Pod);

 

2)  a lag of up to 24 hours of data that can be pulled from the GS-Pod or GS sensor.  Without the logger at the base of the tower to force the sensors and PODs to "sync", the data set extracted using the GS-PAD may end a few hours earlier than when the GS sensors and GS-PODs were actually removed from the tower.  

  

A different approach that overcomes these drawbacks is to bring the GS-Logger to the site at the beginning and end of the measurement period.  During installation, perform the tower sync function.  Then when you are ready to extract the data, bring the logger back out to the site, do another tower sync, and then the data can be removed from the logger [rather than having to tip the tower down and remove the GS sensor(s) and GS-POD(s) to get the data].
