    Performing a Measurement System Power Budget Analyzing a measurement system power budget is a useful practice to help ensure that a proposed system design will meet the monitoring objectives and reliably deliver data. To aid with this, NexSens has developed a power budget tool which can quickly estimate the expected power performance of systems using the most common NexSens buoy platforms, data logger configurations, and commonly integrated NexSens and third-party sensors for deployment locations throughout the world.

    a. Reserve Days refers to how long the system could operate if starting with near 100% battery charge during an extended period without solar charging, or how long a system without any solar charging can be expected to operate. For solar-charged systems, a rule of thumb is to target at least two weeks (14 days) of reserve power.

    Enable Iridium Communication on an X-Series Data Logger Satellite/Iridium transmission is more expensive than other traditional forms of communication (e.g., cellular, radio, Wi-Fi). Therefore, it is imperative that the end-user only transmit the most useful diagnostic and sensor parameters. The CONNECT software can set these parameters and their log/transmission interval before the data logger transfers data to the web.
  • Page 48 3. Cell Signal Strength 4. Cell Status 4) Set Log/Selective Upload Interval(s) The log interval controls the frequency at which parameter data is recorded, and the selective upload interval controls the frequency at which parameter data is transmitted. Users may set parameter data to log internally at a higher frequency while only transmitting a portion of the logged data.

    Iridium Transmission Delay Compared to data loggers utilizing cellular, radio, or Wi-Fi telemetry, Iridium transmission systems have an additional step in the data upload process which may cause a delay in the time it takes from the logger recording a measurement to data being posted on WQData LIVE. Data messages transmitted from the logger’s satellite modem are first packaged as email attachments (SBD file).
