Deep Space Now (DSN) Java Client

This library provides a client for interacting with the API that powers the DSN Now webpage.

Usage

Adding dsn-now-client to your project

First, add the package as a dependency in your project:

Maven:

 <dependency>
  <groupId>net.adambruce</groupId>
  <artifactId>dsn-now-client</artifactId>
  <version>${version}</version>
</dependency> 

Gradle:

implementation("net.adambruce:dsn-now-client:${version}")

Using the Client

To use the client, create an instance of the client and call one of the following methods:

Fetching the DSN Now Configuration

The DSN Now configuration contains basic information about DSN's ground stations, dishes and tracked spacecraft.

DeepSpaceNetworkClient client = DeepSpaceNetworkClient.newDeepSpaceNetworkClient();
Configuration configuration = client.fetchConfiguration();

Fetching the current DSN state

The DSN Now state contains up-to-date state information about ground stations, dishes, spacecraft and communications.

DeepSpaceNetworkClient client = DeepSpaceNetworkClient.newDeepSpaceNetworkClient();
State state = client.fetchState();

Fetching the current DSN state and merging it with the DSN configuration

Combines the above two queries to create a single coherent model hierarchy.

DeepSpaceNetworkClient client = DeepSpaceNetworkClient.newDeepSpaceNetworkClient();
MergedData data = client.fetchMergedData();

Building from Source

To build from source, you will require:

• Java 8+
• Maven

Run the following command (use -Prelease to generate source JAR):

mvn clean install
