In fact, there is no Lightbridge on P3S board, only WiFi link. P3S is more a P2V+ evolution, with some commons with P3 - 4S battery, DJI GO application, propulsion. But more is missing from P3A/P3P than added to P2V+.
First of all, there is no Lightbridge video downlink, but reworked WiFi link that allows for HD video transmission. Lightbridge is a video-oriented technology while WiFi is a general purpose digital link - when used as a dedicated video link it shows some downsides.
Second thing - camera. Some people may be excited with 2.7K mode in P3S, especially when more expensive P3A offers only 1080P. But P3S camera doesn't allow you to use screw-on filters. More important thing - P3S camera uses Panasonic Smart FSI image sensor in place of Sony Exmor R, used in P3A and P3P. First is a typical frontside illuminated sensor (FSI), while second is a backside illuminated sensor (BSI). What does this mean? I won't dig into technical details (you can find it in the Internet), but one of the most important advantages of BSI sensor over FSI is low light performance. In BSI sensors there is much more light captured by each pixel, because it's not hidden by matrix wires.
Third thing - GPS. P3S uses an older, single-constellation (GPS) receiver. P3A and P3P have dual-constellation (GPS and GLONASS) receiver, which results in doubled accuracy and reliability.
Fourth thing - there is no VPS. VPS is not a big deal, but it helps quite significantly when hovering near the ground. Remember - there is no vision sensor only, but also ultrasonic distance sensor. It works even if there is no usable visual pattern on the ground that could be used by VPS.
Fifth thing - RC controller lack of some buttons that are useful, like shutter, video record or two user-defined buttons. It's really good idea to have some things just under the fingertip. RC range is also limited - for a FPV camera multicopter 500-1000 m of control range is definitely not enough.
Phantom 3 Standard is more like upgraded member of Phantom 2 family than simplest member of Phantom 3 family. Please note - you only need to exchange gimbal&camera assembly to upgrade P3A to P3P. At the same time there is not possible to upgrade P3S to higher version in any way. |
