A Real Time Kinematic (RTK) GPS-based track-keeping and berthing control of a small boat is discussed in this work. The Internal Model Control (IMC) method is adopted for the autopilot design. The track-keeping mission is achieved through a sequence of course-changing maneuvers and the ...
Also, not all cars have a built in GPS tracking device in them. You are simply mistaken in this assertion. While more and more cars are getting things like OnStar and other GPS tracking systems with the trend for this type of technology to become standard on all makes and models it is...
Isolation of the boat signature from the sea clutter was obtained by Doppler filtering, using the GPS-estimated Doppler frequency as input. The responses of the three-range cells closest to the GPS range were coherently added to counter range-gate straddling losses. The effects of multipath ...

Design calculations using a hydrodynamic transverse-strip engineering method with semi-empirical correlations were applied to determine suitable dimensions for hydrofoil systems. The boat hulls and hydrofoils were fabricated by laying up carbon-fiber cloth sheets on foam cores or 3D printed profiles. The...
Then the biggest boat project we’ve ever taken on ourselves – installing a high volume water maker / desalinator. A bigger boat means more room for systems and having a virtually unlimited supply of fresh water will be a game changer for our cruising life. But first – we’ve got to ...
With its dual-system capability, you can switch between operating systems with ease, ensuring you have access to the tools and applications you need. The range of processors from Z3735f to core m7y30 provides a spectrum of performance, allowing you to choose the right balance of power and ...

The SMARTBoat 3 platform consists of three layers to contain the water quality sensors, ESCs, battery, GPS, Bluetooth, and main boards as shown in Fig. 5. The first layer (main control box) is a fundamental structure to mount the water quality sensors and tightly fix the thrusters (CW/CC...
Solar-powered boat 1. Introduction Nowadays, the main examples of the negative anthropogenic impact on the Earth are greenhouse gas (GHG) emissions, water pollution, air pollution, and global warming. In addition to other sources of pollution, maritime and aviation transport is responsible for appro...
