The famous car designer Henrik Fisk has established a new electric car company, Fisker. Recently, he began to show some pictures of the company's first electric car.
The electric car, called Fisker EMoTIon, is positioned as a “luxury†in the electric car industry, claiming to be the first electric car to last up to 400 miles (644 km).
The Fisker EMoTIon electric car has a top speed of 259 km/h. Thanks to the new graphene battery technology, the single-charge battery life reaches an astonishing 644 km, and the Bitsla Model S has an additional 136 km. The car battery pack will be produced by Fisker Nanotech, and the compact electric power system layout of the car will further expand the interior space. The body material is made of carbon fiber and aluminum. The lightweight material will give the Fisker EMoTIon better sports performance while reducing the weight of the car.
According to Fisker, the hardware of the Fisker EMoTIon electric car will also support full autopilot functionality, but it is not immediately available. It is reported that the autopilot technology of the Fisker EMotion electric vehicle will be submitted to a third-party company for design and development. Fisker EMotion will be produced in the United States and is expected to be officially launched in mid-2017.
- The Description of GPS Antenna
- GPS is a terminal for positioning or navigation by receiving satellite signals. An antenna is needed to receive the signal. GPS satellite signals are divided into L1 and L2 with frequencies of 1575.42MHz and 1228MHz respectively. L1 is an open civil signal and the signal is circularly polarized. The signal strength is about -166dBW, which is a relatively weak signal. These characteristics decide to prepare special antennas for the reception of GPS signals
- The use of GPS in cars will become more and more common. But the automobile shell, especially the automobile explosion-proof film produces the serious obstacle to the GPS signal. An external antenna with a magnet that attaches to the roof of the car is necessary for a GPS in the car.

The GPS antenna plays a pivotal role in ensuring reliable reception of these satellite signals, even in challenging environments. It is designed to be highly sensitive to the specific frequencies of GPS satellites, namely L1 and L2, enabling it to capture the weak signals emitted by the satellites effectively. The antenna's design focuses on enhancing signal capture while minimizing interference from external sources, such as the metallic body of a vehicle or the shielding effects of an automobile's explosion-proof film.
For automotive applications, GPS antennas are often equipped with a strong magnetic base, allowing them to be securely attached to the roof of a car or any other metallic surface. This placement is strategic as it positions the antenna away from the obstructive materials inside the vehicle, providing a clearer line of sight to the sky and the orbiting GPS satellites. By doing so, it significantly reduces signal attenuation, ensuring accurate and consistent positioning data for the vehicle's navigation system.
Moreover, these external GPS antennas are designed to withstand various weather conditions, including extreme temperatures, moisture, and vibrations, ensuring reliable performance over time. Some advanced models also incorporate features like multi-path mitigation, which helps to filter out reflected signals that can cause positioning errors, further enhancing the accuracy of the GPS system.
In summary, the GPS antenna is a crucial component that enables efficient and accurate reception of satellite signals, especially in automotive applications where signal obstruction is a common challenge. Its specialized design and strategic placement contribute significantly to the overall performance and reliability of GPS-based navigation systems.
