04 05 Introduction Foreword Space technology globally is becoming increasingly accessible as hardware becomes cheaper, more satellites are launched and its applications are improved and expanded. While traditionally sectors like defence and mining have been testing grounds for frontier space technology, recent advances, namely in satellites, have opened a wealth of opportunity for Australia’s rural industries.

12 13 Preface A farmer’s morning in 2050 Jamie Blakeman gets up with the rise of the sun and switches on her computer. A quick check of the water tank levels indicates that tank 6E is getting low, so she opens the irrigation program and transfers 300 L water to it from the upper reservoir. Next, she refreshes the soil moisture map of her property and notices that the light rain squall in the past week has wet the north-western paddock. Seeing that an updated satellite pass has become available, she downloads the new grass quality data and compares it with the soil moisture. The correlation is good. It’s clear that it’s time to move the stock into that pasture. She reconfigures the virtual fencing app and starts the process of moving the stock from paddock 4 across to the pasture. Knowing that it will take half an hour for the animals to be encouraged along by the moving virtual fence, she gets up from her desk and goes into the kitchen for breakfast. After breakfast, she checks the real-time cameras to verify that the stock has moved, checks the soil moisture in paddock 4 and decides to irrigate only the lower third. She switches on the system, setting it for a 30-minute watering. All this is plausible With the immediate operational tasks complete, she turns her attention to longer-term issues of weather prediction for the next through the application week and purchasing fertiliser and seed in preparation for the next of existing technologies, round of planting. All the above is plausible through the application of existing which have the potential technologies, which have the potential to revolutionise the to revolutionise the working day of tomorrow’s farmers. working day of tomorrow’s farmers.

It can be difficult to decide which Resolution: 15-100 m, revisits every eight days. technology is right for the job. Here, individuals need to determine what success would look like and think about what resolution they might need. This might include a farmer asking questions such as: “Do I need to see individual trees?” or “Is it useful to have one image that captures a whole paddock?” It may be necessary to try a few options to find which work best for given needs. Combining different services might provide the most benefit. Figure 02. Landsat imagery of eastern Australia acquired during the January 2020 bushfires.
