In 2024, the Jilin-1 satellite constellation's 0.5m resolution images will be released online for the first time. The resolution of this image is 0.5m, which demonstrates the strong data acquisition and processing capabilities of Jilin-1. This year, the Jilin-1 constellation has added six 0.5m resolution wide-angle satellites, making it unrivaled in large-area coverage. Previously, this was only available in government projects, but now it is gradually being made available to enterprises and individuals. Another exciting piece of news is that this high-resolution nationwide image will be continuously updated approximately every six months. Changguang Satellite Technology, the leader in China's commercial satellites, truly deserves a big respect.
For the nationwide range from 2023-2024, the APP offers an unlocking coupon, which can be used to unlock new images of specific areas from the previous quarter or images from a fixed quarter that is meaningful to the user. For example, the editor used an unlocking coupon to access new images from September 2024 of their hometown. This is a good option for those who wish to obtain more recent images of specific regions. For viewing a particular park or residential area, the cost is roughly in single digits, and various promotional activities are available to make the most of it.
This update includes a particularly interesting point of interest subscription feature. The core logic of this function is that after focusing on and selecting a subscription area, whenever one of the more than 100 Jilin-1 satellites captures an image, whether or not there are clouds, the processed image is immediately pushed to the user's phone. Subscription push features have previously appeared on some platforms but typically at 2m or lower resolution, which wasn't very valuable. With over 100 sub-meter satellites providing immediate push notifications, it is akin to having "space surveillance," sparking a wide range of imaginative possibilities.
With time-series images, looking at some well-known locations becomes particularly interesting. There are more than a dozen categories, including historical culture, famous landmarks, outdoor adventures, renowned universities, large airports, and famous ports. For instance, the Forbidden City's images include 129 periods, you can see the parking status of planes in 64 images of Beijing Daxing Airport, observe the changes in the number of containers at Zhoushan Port, and even check the construction progress of school dormitories. More impressively, nearly 200 of these locations have been integrated, with the combined images possibly exceeding 10,000, and many overseas locations are included as well.
