The National Data Buoy Center (NDBC) has taken delivery of a recently developed Local User Terminal (LUT;) for use with the National Oceanic and Atmospheric Administration (NOAA) satellite Data Collection and Platform Location System. Tests were conducted in those produced by Service Argos to determine if the LUT could be which the accuracy of the LUT position fixes were compared with used for a moored buoy application. Analysis of initial test results and discussions with the manufacturer produced techniques for improved operation. These techniques were implemented and the results are presented and compared with those from the original test and from Service Argos. Additional modifications to provide possible improved position accuracy and system performance are also described.

Technological advances are transforming agriculture in many parts of the world. Despite the importance of agriculture to its economy, Australia lags behind other advanced economies in the adoption of digital agricultural technology. The country risks losing its comparative advantage due to a weak policy around digital agriculture. This study combines network analysis and natural language processing to assess 654 public submissions to six government inquiries addressing agricultural innovation, the digital economy, and rural broadband communication networks, held between 2016 and 2018. The analysis shows there is no consistent narrative driving policy development around digital agriculture. A fragmented policy landscape is a concern because it means that current and emerging policies may not address key issues, resulting in sub-optimal outcomes for Australian agriculture.
