Mads Tech Says
The Ascent Goggles are the first FPV Goggles from Caddx designed for the Ascent Digital FPV system and Protos Drone.
Ascent is Caddx’s second digital FPV system offering 60fps digital FPV at a lower price point. Ascent is a 5.8Ghz 2 way transmission system based around the Artosyn ARLink AR803X/AR8030 chipset. It supports transmission bandwidth of 5/10 & 20Mhz and a maximum bitrate of 25Mbps.
Other produces using the AR803X series do support higher bandwidth however its not clear if the Ascent limitation is chipset or design related.
Externally these goggles are VERY similar to the Caddx Avatar Goggle L using the same external housing (colour change) and optics. However internally the main PCB has been replaced with new one based on the new RF chipset.
These goggles also only have 2 antennas rather than 4 like the Goggles L.
Caddx Ascent – Caddx FPV Say
Immersive Wide-Angle Vision
Experience an expansive field of view that pulls you deeper into every flight.
Built-In DVR with 1080p Recording
Capture every flight in high definition, directly to your TF card.
Built-In High-Gain Antennas
Enjoy strong, stable, and interference-free signals during flights.
Customizable FPV Goggle Lenses
Supports nearsighted, farsighted, and blue light-blocking lenses.
Compatibility
The Ascent FPV Goggle is only compatible with Caddx Walksnail Ascent VTX.
CaddX have stated they intent to release a VRX module and other goggles in the future.
Ascent VTX and Goggles are not compatible with the Avatar HD products from Caddx.
Antenna’s
The Ascent goggles have two internal patch antennas mounted at the front of the goggles. There are not omnidirecitonal antennas built into these goggles.
Head Tracking
Whilst not listed in the spec the CaddX Ascent Goggles appear to have the same headtracker fitted as the Goggles L. This is mounted on the Power PCB
Caddx Ascent FPV Latency
I my testing I have found the latency on the Ascent system to be higher than expected for a 60fps system. It is not clear if this is VTX or Goggles related at this time.
The following tests were performed on Ascent with the Goggles Ascent on initial release firmware.

Artosyn – Shanghai Coolcore Microelectronics Co., Ltd ARLink AR8030 / AR8030 Series
A number of other consumer drone products use Artosyn based chipsets including Caddx Avatar HD that Uses the AR9201 series.
The AR8030/AR803X supports a range of 150Mhz to 7Ghz, up to 160Mbps data rates and offers up to 15Km range. At launch Ascent supports 5/10/20Mhz Carrier bandwidth on download and 5Mhz on upload modes and a maximum bitrate rate of 25Mbps.
Other products including the Potensic Atom 2 and the Antigravity A1 360 drone also used the Artosyn AR803X series of chipset.
