NASA Spacecraft Telemetry

Lightstreamer has been procured by NASA Mission Operations Directorate via Lockheed Martin. The Mission Operations Directorate is evaluating the product for distribution of real-time spacecraft telemetry data. [Read the press release]

Telemetry is a kind of application where being able to push real-time data through the Internet, to any web browsers and smartphones, is a new fundamental feature.

The "Push Paradigm" (also know as "Comet") originated in the Financial Serivces industry, where Lightstreamer was the very first solution, back in 2000, that was able to update stock market prices in real-time using only html and javascript. Now, more and more application domains are taking benefit from this paradigm, including aerospace, military, gaming, sporting, and entertainment.

Meta-Push, COMMAND Mode, and the New Flex Portfolio Demo

On of the advanced features of Lightstreamer that sometimes is not notice when first dealing with the product is COMMAND subscription mode. It is a very handy way of pushing not only changes to the data rows, but even changes to the table itself (in terms of adding and removing rows).

A typical example of this is a trading portfolio. You have a table with the list of stocks currently in your portfolio. The value of such stocks keep changing based on the market, so some columns keep being updated. At the same time, you may sell or buy some stocks, resulting in removing or adding rows to the table. You want such changes to be pushed to the front-end in real-time too. A nice example of this is the online Portfolio Demo.

New Excel Demo Available

Excel spreadsheets are often the main means used by professional traders to analyze data and make decisions. Being able to inject real-time data into Excel means boosting the capabilities of the traders.

We have hosted a Lightstreamer-to-Excel demo for a long time, but we never provided the source code. We have now reengineered such demo and published online together with full source code. This way, Lightstreamer developers will have a good starting point to implement their own Excel applications.

Android Demo Available

The Android operating system is spreading to more and more smartphones. Being able to deliver real-time updates to applications running on Android phones may be a crucial feature for many scenarios (from financial applications, to social and collaboration tools).

Lightstreamer is a perfect means to push data updates to any application/device connected to the Internet, including Android phones. For this reason, we have decided to release an Android example for Lightstreamer, together with full-source code.

This Android app, developed in Java, uses the Lightstreamer Java Client library to subscribe to 15 stock prices (as most of our typical "Stock-List Demos" do). The price updates are received in real-time, with very low latency, through a connection based on HTTP streaming.
