If you ’re piloting a mad home brew quadracopter , sooner or later you ’re going to want to be capable to pilot your UAV beyond where you may see it . And for more accurate trailing , your ordinary GPS liquidator ’s five - meter truth just ai n’t gon na curve it . A duo of enterprising engineers have successfullyKickstarteda new liquidator called the Piksi , which they claim is accurate down to just a few centimeters .
GPS is a pretty remarkable technology , but there are a number of limitation to the way your position is calculated . First of all , the turn duration of a GPS code is about 300 meters , which mean that even with sign from four satellite your berth can only be calculated to within a few meters — at substantially . moreover , the ionosphere introduces stay into the sign , which increases error .
The Piksi extenuate these problem and better truth and precision in two way . In addition to measuring the GPS code beam down by satellite , it also value the phase of the 19 centimeter wavelength of signal the computer code is carried on . Using a trivial algorithmic processing , the Piksi can use this information to improve location truth . what is more , the Piksi system use an additional receiver as a reference point to help palliate the effect of the ionospheric delay .
The project has already been fully funded , but you may still pick up a unspoiled plenty on the Piksi . single social unit during the Kickstarter effort cost $ 500 , compared to the anticipate $ 900 price once the product goes into production . Usual Kickstarter caveats utilize . corrupt at your own risk .
This unit trusted is n’t inexpensive by traditional standards , but moot a corresponding product for professional applications unremarkably costs many thousands of dollar mark , it ’s relatively sensible . Plus , if you ’re flying a couple of grand Charles Frederick Worth of drone up in the air , it ’s probably worth knowing EXACTLY where your money is flying — lest all that cash fly away .
