how to extract software from satellite receiver

OTN maintains acoustic telemetry analysis packages designed to work with this data format available in: Additionally, the files are often too big to be opened and analyzed easily in spreadsheet programs (ie Excel), instead OTN recommends using a CSV viewer (ie Notepad++) or directly into a programming software such as R or Python. If you open a file with fractional seconds in Excel, it is possible these dates will appear invalid (ex: ). Researchers then have the option of rounding the detection times during analysis. Since the receiver has recorded this extra information, OTNDC provides it in the Detection Extracts with the same level of precision. This information is important in detailed positioning studies using certain receiver models, and so is retained during data processing. It should be noted when reviewing your detection extract that some acoustic telemetry processing software (ex: InnovaSea's FATHOM) extract fractional seconds from the receiver's detection log. To see when each record was last added or changed, please refer to the DateLastModified column. These detection extracts contain only the detections for the year corresponding to the suffix on the file name.ĭetection extracts for previous years are updated when new detection data / tag records are loaded into the database and are matched to your project.

OTN and all of its partner nodes create detection extract files on a semi-regular basis, every ~3 months, following a cross-node coordinated detection matching event known as a Data Push.
