Line 4: ==Technology== Electronic chartplotters are by nature [[Central Processing Unit\|CPU]] (and [[General-purpose computing on graphics processing units\|GPU]]) intensive applications. Chartplotters need to retrieve the Navigation Signal ([[Galileo (satellite navigation)\|Galileo]], GPS, [[GLONASS]], [[Wide Area Augmentation System\|WAAS]] etc) signal and overlay that on a map. Map updates on dedicated hardware typically have screen refresh rates from 5hz to 30hz. Some navigation software can run on standard computers (and mobile phones, etc) but most higher end systems are dedicated hardware. Especially when the chartplotter generates three-dimensional displays, as used for fishing, considerable processing power and video memory may be required.
