How to generate data from Space-Track website using api
问题
我想从网站https://www.space-track.org/documentation#/api 获取数据,该网站提供多个API,可以使用特定的API(如SATCAT和TLE)生成数据,我不确定如何做到这一点,有人可以帮助我使用这两个API生成数据吗?
非常感谢提前帮助。
我不太了解如何使用API。
英文:
I want to fetch data from the website https://www.space-track.org/documentation#/api
the above website offers multiple API's to generate data using specific API's like SATCAT and TLE, I am unsure how I can do that, can someone help me on this to generate data using those 2 API's.
Many Thanks in advance
I don't have much knowledge in using API's

假设您已经具备验证 API 请求的凭据:
-
选择一个类似于 Python 中的 requests 的 HTTP 客户端库。
-
发起 API 请求:
> SATCAT API:SATCAT API 允许您检索卫星目录数据的信息。要获取 SATCAT 数据,请构建一个带有所需参数的 API 请求 URL,并向 API 终点发送一个 HTTP GET 请求。例如,要获取特定卫星的详细信息(通过其国际指示符 INTDES 进行标识),您可以发起如下请求:
requests.get(https://www.space-track.org/basicspacedata/query/class/satcat/INTDES/{satellite_intdes}/orderby/SATNAME/format/json)
用实际的卫星国际指示符替换 {satellite_intdes}。
> TLE API:TLE(两行轨道要素)API 允许您检索 TLE 格式的卫星轨道数据。要获取 TLE 数据,请构建一个带有所需参数的 API 请求 URL,并向 API 终点发送一个 HTTP GET 请求。例如,要获取特定卫星(通过其 NORAD 目录编号进行标识)的最新 TLE 数据,您可以发起如下请求:
requests.get(https://www.space-track.org/basicspacedata/query/class/tle_latest/NORAD_CAT_ID/{norad_cat_id}/orderby/EPOCH desc/limit/1/format/tle)
用实际的 NORAD 目录编号替换 {norad_cat_id}。
-
处理 API 响应:一旦您收到 API 响应,您可以根据提供的格式(例如 JSON 或 TLE)解析和处理数据。您可以从响应中提取所需信息,并根据需要在发票应用程序中使用它。
以下是使用 Python 和 requests 库从 Space-Track API 获取数据的示例代码:
import requests
# API 凭据
username = "your_username"
password = "your_password"
# Space-Track API 的基本 URL
base_url = "https://www.space-track.org"
# SATCAT API 终点
satcat_endpoint = "/basicspacedata/query/class/satcat/INTDES/{satellite_intdes}/orderby/SATNAME/format/json"
# TLE API 终点
tle_endpoint = "/basicspacedata/query/class/tle_latest/NORAD_CAT_ID/{norad_cat_id}/orderby/EPOCH desc/limit/1/format/tle"
# 获取 SATCAT 数据的函数
def fetch_satcat_data(satellite_intdes):
# 构建 API 请求 URL
url = base_url + satcat_endpoint.replace("{satellite_intdes}", satellite_intdes)
# 发送带有验证的 GET 请求
response = requests.get(url, auth=(username, password))
# 检查请求是否成功
if response.status_code == 200:
data = response.json()
# 根据需要处理数据
return data
else:
print("获取 SATCAT 数据失败。状态码:", response.status_code)
return None
# 获取 TLE 数据的函数
def fetch_tle_data(norad_cat_id):
# 构建 API 请求 URL
url = base_url + tle_endpoint.replace("{norad_cat_id}", norad_cat_id)
# 发送带有验证的 GET 请求
response = requests.get(url, auth=(username, password))
# 检查请求是否成功
if response.status_code == 200:
data = response.text
# 根据需要处理数据
return data
else:
print("获取 TLE 数据失败。状态码:", response.status_code)
return None
# 示例用法
satellite_intdes = "ISS"
satcat_data = fetch_satcat_data(satellite_intdes)
if satcat_data:
print("卫星", satellite_intdes, "的 SATCAT 数据:", satcat_data)
norad_cat_id = "25544"
tle_data = fetch_tle_data(norad_cat_id)
if tle_data:
print("NORAD 编号为", norad_cat_id, "的 TLE 数据:", tle_data)

英文:
Assuming you already have credentials to authenticate the API requests:
-
Choose an HTTP client library like requests in python
-
Make an API request:
> SATCAT API: The SATCAT API allows you to retrieve information about satellite catalog data. To fetch SATCAT data, construct an API request URL with the desired parameters and send an HTTP GET request to the API endpoint. For example, to fetch the details of a specific satellite identified by its International Designator (INTDES), you can make a request like:
requests.get(https://www.space-track.org/basicspacedata/query/class/satcat/INTDES/{satellite_intdes}/orderby/SATNAME/format/json)
Replace {satellite_intdes} with the actual International Designator of the satellite you want to fetch.
> TLE API: The TLE (Two-Line Elements) API allows you to retrieve satellite orbit data in TLE format. To fetch TLE data, construct an API request URL with the desired parameters and make an HTTP GET request to the API endpoint. For example, to fetch the latest TLE data for a specific satellite identified by its NORAD Catalog Number, you can make a request like:
requests.get(https://www.space-track.org/basicspacedata/query/class/tle_latest/NORAD_CAT_ID/{norad_cat_id}/orderby/EPOCH desc/limit/1/format/tle)
Replace {norad_cat_id} with the actual NORAD Catalog Number of the satellite you want to fetch.
-
Handle the API response: Once you receive the API response, you can parse and process the data based on the format provided (e.g., JSON or TLE). You can extract the required information from the response and use it in your invoicing application as needed.
Here's an example of how you can fetch data from the Space-Track API using Python and the requests library
import requests
# API credentials
username = "your_username"
password = "your_password"
# Base URL for Space-Track API
base_url = "https://www.space-track.org"
# SATCAT API endpoint
satcat_endpoint = "/basicspacedata/query/class/satcat/INTDES/{satellite_intdes}/orderby/SATNAME/format/json"
# TLE API endpoint
tle_endpoint = "/basicspacedata/query/class/tle_latest/NORAD_CAT_ID/{norad_cat_id}/orderby/EPOCH desc/limit/1/format/tle"
# Function to fetch SATCAT data
def fetch_satcat_data(satellite_intdes):
# Construct the API request URL
url = base_url + satcat_endpoint.replace("{satellite_intdes}", satellite_intdes)
# Send GET request with authentication
response = requests.get(url, auth=(username, password))
# Check if the request was successful
if response.status_code == 200:
data = response.json()
# Process the data as needed
return data
else:
print("Failed to fetch SATCAT data. Status code:", response.status_code)
return None
# Function to fetch TLE data
def fetch_tle_data(norad_cat_id):
# Construct the API request URL
url = base_url + tle_endpoint.replace("{norad_cat_id}", norad_cat_id)
# Send GET request with authentication
response = requests.get(url, auth=(username, password))
# Check if the request was successful
if response.status_code == 200:
data = response.text
# Process the data as needed
return data
else:
print("Failed to fetch TLE data. Status code:", response.status_code)
return None
# Example usage
satellite_intdes = "ISS"
satcat_data = fetch_satcat_data(satellite_intdes)
if satcat_data:
print("SATCAT data for", satellite_intdes, ":", satcat_data)
norad_cat_id = "25544"
tle_data = fetch_tle_data(norad_cat_id)
if tle_data:
print("TLE data for NORAD ID", norad_cat_id, ":", tle_data)
